Re: Help with Kaiser's Highway Star repro

As far as I can tell, the game writes: * cipher[bank] to $4A00+cipher[bank] (where those values range from 0xB2 through 0xCE) * cipher[bank] to $6E36 * bank to $6000 * mirror to $C0FF There is a plain UNROM mapper hack of the game present in GoodNES, which seems to work but has conspicuous glitches...

Re: Multicart doesn't work on famicom

1. Detect the contact between goldfinger and slot 2. Check the power supply system of the console Although the DIP chip card is very expensive in China, it is only suitable for collection, because some of the large number of DIP chip CARDS are on low voltage machines, the execution is problematic 1....

This card is different from UxROM

UxROM, switch 8000, 16K data, using address 8000-FFFF

KS7013B, switch 8000,16 K data, using addresss 6000-7FFF

And 8000-FFFF is the control of mirr

Re: Dragon Ball 3 - Gokuu Den PCB TTL

Thanks to zxbdragon photos I was able to rev-en this PCB. Surprisingly I was almost 100% accurate with my guesses, here are differences: * CHR-ROM order is 100069C + 100068C, not vice versa * MJ338986 is 74191 with CLK and /CNTEN pins swapped (pin4=CLK, pin14=/CNTEN) * $600A.0 must be written with ...

Re: Dragon Ball 3 - Gokuu Den PCB TTL

Circuit reason? My best guess is that something is delaying the output of PRG ROM substantially, relative to the original cart. When the Game Genie has a password that relies on a "compare" byte, there is some sort of timer inside the Game Genie that it uses to detect when it should emit its replac...

Re: Dragon Ball 3 - Gokuu Den PCB TTL

We don't know how the Game Genie handles the race-y analog "detect the current ROM output value"... Maybe the reproduction here has some sort of timing problem? If so, since your GG codes are in the FCG's fixed bank, you could try removing the compare part of the GG code: OXVSKSIV → OXTSKS NNVSSIZX...
