At write protection control part 54, have two registers 61,62 that data setting is used, calculation loop 64, resulting in closes at two registers 63,65, and comparative result closes at register 67.

The inside that Figure 20 represents to become the control part 71 of game card casket 70 feature portions constitutes calcspar.At control part 71, has interface 73, write protection control part 74, reservoir 75.Interface 73 is the interface between the inside write protection control part 74 of the CPU51 of rewriting machine 50 and control part 71.Receiving data-signal DT and other signals between CPU51 and the interface 73 and between CPU51 and the interface 53 equally.

Write protection control part 74 except that preventing incorrect writing, is still brought into play the device part of center function.Its main portion and write protection control part 54 have same formation.Promptly, have two registers 81,82 that data setting is used at write protection control part 74, calculation loop 84, resulting in closes at two registers 83,85, and comparer 86, comparative result close at register 87.

At write protection control part 74, has control signal efferent 88.Control signal efferent 88 to memory controller 75, is used to export inner flash control signal CNT1 and writes enabling signal WPM.Write enabling signal WPM, send and agree the writeable signal that is indicated to flash of light reservoir 72, inner flash control signal CNT1 is used to indicate that flash of light reservoir 72 checks appointment codes such as begins.

Reservoir control part 75 according to the signal by write protection control part 74 and CPU51, is used to control the device part that flash of light reservoir 72 write and read action.Omit diagram, but, have address decoder and be used for decode address signal ADR1, specify the address of flash of light reservoir 72 to be exported as flash address signal ADR2 at reservoir control part 75.At reservoir control part 75, has reservoir conversion generating unit in order to make reservoir conversion corresponding to card casket regulation.Card casket specification as Fig. 9 is selected loop 31.

To flash of light reservoir 72, except that input data signal DT and flash address signal ADR2, also has flash control signal CNT2 by reservoir control part 75.Flash control signal CNT2, the reservoir 72 that is used to glisten writes and reads the signal of action.Data-signal DT between reservoir control part 75 and flash of light reservoir 72, carries out two-way reception.

Figure 21 and 22, expression is connected to rewriting machine 50 with game card casket 70, when routine data is written to the flash of light reservoir 72 of game card casket 70, the action flow chart of the combination of rewriting machine 50 and game card casket 70.According to this process flow diagram, rewrite the action of machine 50 and game card casket 70 each one as detailed below.

Begin to handle, at first, in step S1, rewrite medium, even game card casket 70 is inserted into rewriting machine 50, the result, rewriting machine 50 and game card casket 70 interconnect.

Then, in step S2, rewriting machine 50 power supplys are inserted into.Reservoir control part 75 is in order to carry out the action of reservoir conversion.Afterwards, execution in step S3, S4.

In step S3, CPU51 writes each 1byte data at register 61,62.Meanwhile, in step S4, CPU51 writes data to register 81,82, respectively be written to register 61,62 in the data of identical each 1byte.As a result, the data of the 1byte that register 61 and register 81 are used to keep identical, and the data of the 1byte that register 62 and register 82 are used to keep identical.

Then, in step S5, calculation is carried out according to the data of register 61,62 in calculation loop 64, and will result in and be written to register 65.Simultaneously, in step S6, calculation loop 84 is carried out calculation according to the data of register 81,82, and the data that result in is written to register 85.Rewriting machine 50 and game card casket 70, if both sides are regular device, the formation in calculation loop 64 and calculation loop 84 is identical, and this moment, identical calculation was carried out in both sides' calculation loop 64,84, and the data that are written into two registers 65,85 are also identical.

Figure 23 represents the circuit diagram that the inside in regular calculation loop 64 (and 84) constitutes.Calculation loop 64 has 8 exclusive logics and circuit.And in this side input, input has the 1byte data A that keeps register 61, and (=A0～A7), and in the other party input, input has data the B (=B0～B7) of the 1byte that remains in register 62.

As exclusive logic with make (=C0～C7), be input to register 65 as output signal by the 1byte data C after calculating.If rewriting machine 50 and game card casket 70 regular devices are equipped with in the both sides in calculation loop 64,84, constitute circuit diagram as Figure 23.

Then in step S7, CPU51 reads the data that are stored in register 85, and is written to register 63.Meanwhile, in step S8, CPU51 reads the data that are stored in register 65, and is written to register 83.

Whether in step S9, the data that comparer 66 will be stored in two registers 63,65 are compared, consistent in order to judge.And, the data of result of determination are written to register 67, communicating data is to CPU51 afterwards.

With the step S9 while, in step S10, the data that 86 pairs of comparers are stored in two registers 83,85 are compared, whether consistent in order to judge, and, make the data that show result of determination, be written to register 87, data are communicated to control signal efferent 88 and CPU51 afterwards.

Be written in the data behind the register 67,87, if the data of the inconsistent result of determination of performance, execution in step S11 are arranged.At step S11, CPU51 stops whole processing.Again, control signal 88 is in order to keep not sending the state that writes enabling signal WPM.Reservoir control part 75 is not imported and is write enabling signal WPM, so, if write permission signal WR, data-signal DT, address signal ADR1 etc., do not write flash of light reservoir 72 by 50 inputs of rewriting machine yet.The reservoir 72 that promptly glistens is positioned over to be forbidden under the write state.

Be written into the data behind the register 67,87, if the performance of the data of result of determination is consistent, execution in step S12 then.In step S12, control signal efferent 88, the data according to being written into behind the register 87 write enabling signal WPM in order to output.As a result, reservoir control part 75 reservoir 72 that will glisten is arranged to write state.But, only can write, and, be forbidden by the writing of CPU51 by reservoir control part 75.

Control signal efferent 88, output write enabling signal WPM simultaneously, with the signal that indication flash of light reservoir 72 begins to check, are exported as inner flash control signal CNT1.Reservoir control part 75 responds to this signal, and to flash of light reservoir 72, carries out predetermined data and write.Predetermined data are prepared in advance in reservoir control part 75.

Then in step S13, reservoir control part 75 is read the data that are written into flash of light reservoir 72, simultaneously, data after reading and the data of being scheduled to is compared.And result relatively sends to CPU51.Result relatively is identified inconsistent, and then CPU51 judges that the hardware of flash of light reservoir 72 has unusually, and carries out above-mentioned step S11.Simultaneously, reservoir control part 75, to write enabling signal WPM identical with input not, forbids being written to flash of light reservoir 72.Result as a comparison confirms when consistent, then execution in step S14.

At step S14, reservoir control part 75, the reservoir 72 that will glisten, but be arranged to write state by CPU51.Then, CPU51 carries out predetermined data and writes flash of light reservoir 72.Afterwards, in step S15, CPU51 reads the data that are written into flash of light reservoir 72, and the data after will reading are simultaneously compared with the data of being scheduled to.

When comparative result was inconsistent, CPU51 judges at flash of light reservoir 72 or about write activity one of them hardware such as reservoir control part 75 to flash of light reservoir 72 to be had unusually, carries out aforesaid step S11.At this moment, CPU51 control reservoir control part 75 makes reservoir control part 75 forbid being written to flash of light reservoir 72.When comparative result is consistent, execution in step S16 then.

Step S16 makes the routine data of receiving and keeping in storage part 57, is written to flash of light reservoir 72 by CPU51.Make the routine data that is stored in flash of light storage 72, be rewritten as new routine data.Stop rewriting, then stop all handling.

In step S3, S4, when not carrying out data setting, in step S5, S6, when resulting in not sense data, or, in step S7, S8, during the result's that do not perform calculations setting, also in the judgement of step S10, S11, resulting in of the two is generally inconsistent, so as a result of, forbid being written to flash of light reservoir 72.

As mentioned above, in the present embodiment, rewriting machine 50 and game card casket 70, at least one side of its device can prevent to be written to flash of light reservoir 72 when incorrect (irregularia).

According to above action, the reservoir control part 75 of game card casket 70 is between a plurality of states of suitable conversion.Figure 24 illustrates the transition diagram of this state.Insert power supply, the pattern of reservoir control part 75 is, at first is initial model M1, that is, initial model M1 becomes omission.This initial model M1 makes the reservoir conversion.For the details of reservoir conversion, continue to quote Figure 10, illustrate.The explanation of step S2 is omitted, but the reservoir conversion is when undesired, and reservoir control part 75 forbids writing flash of light reservoir 72.

Initial model M1 is from step S1～S10, corresponding to the action of reservoir control part 75.Among the step S10, when comparative result is inconsistent, or above-mentioned reservoir conversion is undesired when carrying out, and pattern is transformed into by initial model M1 and sets pattern M2 again.Set pattern M2 again, forbidding being written to flash of light reservoir 72, stopping all actions simultaneously.Set pattern M2 again, the operation of not set releasing by the outside is again exceeded, and is not transformed into initial model M1.

Comparative result in step S10, if no problem, then pattern is transformed into the reservoir school by initial model M1 and looks into pattern M3.Be transformed into the reservoir school and look into pattern M3, be written to flash of light reservoir 72 by reservoir control part 75, but be under an embargo by writing of CPU51 by reservoir control part 75.

Reservoir school facies model M3 is corresponding to the action of step S12～S13.And if result of determination has problem, then pattern is transformed into and sets pattern M2 again according to step S13, if no problem then is transformed into reservoir Overtype Mode M4.

Reservoir Overtype Mode M4 is written to flash of light reservoir 72 by the CPU51 permission.And, carry out the processing of step S14～S16.That is, by CPU51 the glisten inspection of reservoir 72 and the rewriting of routine data.

In step S15,, then be transformed into and set pattern M2 again in this time point pattern if flash of light reservoir 72 check results have problem., then after carrying out the routine data rewriting, be transformed into and set pattern M2 again if check no problem at step S15.And pack game card casket 70 into game ontology when using, pattern is transformed into initial model M1.That is, among the pattern M1, use as game machine usually in the early stage.

In reservoir Overtype Mode M4, reservoir control part 75, the reservoir 72 that will glisten is arranged to readable doing well, and the routine data of receiving and keeping in flash of light reservoir 72 can be read into game ontology.The reservoir control part 75 of game card casket 70 is used to change a plurality of states.

Above-mentioned explanation shows game card casket 70 and rewriting machine 50, as the example that key element constituted of game program supply system.Be not limited to game program data, in general, have semiconductor memory routine data is stored as and can rewrites, and with portable rewriting medium, reach at this and rewrite the rewriting machine that medium are rewritten routine data, identical respectively at game card casket 70 and rewriting machine 50 structures.That is, the present invention is not only applicable to game program supply system, and the general procedure replacement system also is suitable for.
