Re: Irem H3001 - pinout

I assume you have seen this but just in case https://wiki.nesdev.com/w/index.php/INES_Mapper_065 Spartan X2 writes to an undocumented address at least once, $9002 iirc. I did a mmc3 conversion and simply omitted that write and had no consequences as far as I know. Would be interested if you can figu...

Re: Trying to make a NES repro with a "not supported for guessing" board

Yeah sorry i never got around to the logic for guessing 2.0 roms. Seems like those are more common now, i should fix that.

Looking at your output it should be standard unrom.

Re: Nes Noob Repro Starter help

If you're just starting and trying to get a handle on what you're doing, maybe pick a more straight forward application like simple nrom or cnrom. There are caveats with basically everything else that can be dealt with when you have a grasp on what you're doing.

Re: Nintendo "Gigaleak"

Saw a tweet there was another file dump. This one includes the disk system lot check, including an unreleased balloon fight port. Sounds like they're in an internal format but can be converted to fds.

Neo geo also uses db15 plugs right? Are there any neo geo light gun games?

Re: Mike Tyson's Punch-Out Disassembly

Well, I went through and completed the commenting of Glass Joe's right hook data. Not too interesting but I pulled apart a lot of the code to understand it. It's a good start on understanding the code that controls the opponent states. I reverse engineered about 2/3 of the subroutines that control ...

Re: Looks like NESCartDB is down (again)...

As compressed XML, it's about 300K. But there are probably more efficient ways to encode the same data. is ok to ask for a copy of that? if you're thinking js interface, json data format is much more efficient storage wise than xml. i'm a bit behind on current client storage/db approaches otherwise.

Re: Mike Tyson's Punch-Out Disassembly

Are you working on the -0 or -1 rom? Curious if you could determine what was changed. There's also the gold famicom punchout, wonder if there were any changes from that.

Re: Mike Tyson's Punch-Out Disassembly

Pretty cool! If you weren't aware of it already, you might be interested in the Playchoice-10 version of the game (and is the only PC10 game that's not 100% identical to the NES carts). It includes battery-backed RAM, and records the players initials and the shortest match times. The only way to vi...

Re: making NAMCOT 163 / N106 dev-cart

Sorry to revive this thread, but a lot of the images that accompanied the discussion are no longer visible. Does anyone have any advice for mapping the CHR and PRG on a 163? I'd like to see what the wires/pinouts are and the only visible pics are the top side of the zif sockets (and it's way too ti...

Re: Expanded ROM works in Mesen, Emuhawk, FCEUX but not QuickNes

What's the address for Init? Does that sub initialize the stack? Are you possibly wiping your return from jsr address?
