Re: Kazzo USB rom dumper / dev cart programmer

Just change the header to mapper 87, instead of mapper 101. (What emulator are you using?) Basically: mappernum = 87 [...] cpu_write(d, 0x6000, ((i & 2) >> 1) | ((i & 1) << 1)); mappernum = 101 [...] cpu_write(d, 0x6000, i); Thank You.. I Couldn't figure out how to Dump my Mapper 87 games til I saw...

Re: Writing CHR to UNROM Board With Kazzo INL/Retro Programm

I do have a unrelated question. On SNES boards it says they can be reprogrammed ~100,000 times. How many times can you reprogram the NES Flash Boards? The NOR flash used in our NES boards has same ~100,000 erase/write cycle endurance. It's far more than you will be able to humanly achieve. Awesome ...

Re: Writing CHR to UNROM Board With Kazzo INL/Retro Programm

Yeah, there's very little reason for emulators to reject mapper 2 + 8k CHR-ROM, even though Nintendo never made such a thing. ...but the board in question has RAM on it. How did you get around the fixed bank of UNROM to create such a loader for a NROM game on a UNROM mapper? If he did, it was proba...

Re: Writing CHR to UNROM Board With Kazzo INL/Retro Programm

UNROM has CHR-RAM, you can't flash it. The software has to fill it up while the NES is running. UNROM can't have 32k CHR either because it has no CHR banking. 8k is all that is possible. As rainwarrior pointed out, erasing/flashing Chr on a board with CHR-RAM doesn’t make sense. Sounds like you wer...

Writing CHR to UNROM Board With Kazzo INL/Retro Programmer.

I recently got my UNROM Flash Board, and am able to program it as long as I only write PRG when I write CHR it says verify OK but I load the programed cart in my Console and there is no CHR, and I think but am not sure, my UNROM board is suppose to have at least 8kb CHR. I can erase PRG but when I t...

Re: Patch Raw Cheat Codes to NES Game

Is there a reason you haven't named the game in question, or described what this code is supposed to do in it? We can't share ROMs here, but there's no problem with talking about them, and I'm not volunteering anybody but there's a good chance someone here could figure out whatever it is in a matte...

Thanks for the Info, I tried everything I could but still couldn't locate the Ram Address that it effected.

Re: Patch Raw Cheat Codes to NES Game

A skilled person could patch it into the game. It's far more complicated than you think. 402 isn't the 0x402nd byte in the ROM. It's a RAM address that might be written to by hundreds of places in the ROM...or only 1 or 2. Depending on the game. It's much much easier to do it an emulator, and use a...

Re: Kazzo USB rom dumper / dev cart programmer

The txc_79 script that I have found on-line writes the CHR bank number to address $4200, which is not what the board expects according to the nesdev wiki . The game writes to $4120 as well, not to $4200. Assuming your mapper 79 dumping script looks like the one I linked to, replace cpu_write(d, 0x4...

Re: Kazzo USB rom dumper / dev cart programmer

What publisher is your F15 City War cart from? There are relases by Idea-tek/TXC, AVE, and Gluk Video, with Idea-tek's original release being undumped. AVE should use Mapper 79, Gluk Video mapper 36 or 79, while Idea-tek's mapper is unknown but probably 136, which might be dumped with the Mapper136...

Re: Kazzo USB rom dumper / dev cart programmer

[EXP283] must be some sort Lock Out Chip Don't think so. You've read the thread. Like Kevtris concluded, I think the cost of getting a new run of Mask ROMs made must have been expensive enough that it was cheaper to get an IC that patches things than to make get an entirely new production run made....
