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

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 ...

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.

FrankWDoom, I'm not sure which ROM I'm working with. How do you tell? Its not the gold one. That one was a Japanese release, right? yes, gold was japan only and did not have tyson here's what i have for roms Mike Tyson's Punch-Out!! (JU) (PRG0) [!].nes CRC32 prg: 8DB6D11F chr: 570B48EA data: 92A218...

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.

Eprom pin 22 leave down and pin 24 wire to hole 31. Everything looks ok i think

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...

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...

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

@tepples my suggestion was geared towards preventing new users from creating spam topics. It doesnt address anything regarding posting in existing topics, but As far as copying posts to unlock topic creation, maybe limit new users to a max number of posts per day? The idea is to allow users a reason...

Is it possible to restrict users from creating new topics until they meet a time/post count threshold? Maybe having mods approve topics from new users if they are valid before they are given free reign? If we're adding mods even something like a time delay auto approve giving someone a chance to cat...

Haven't had a chance to investigate myself but the master rom list sounds interesting. Possibly some unavailable or even unknown games in there?

when i get the ram chip on battery power, i need to add a resistor to put the ram in standby when powered down. I'm guessing I'll want to separate /OE and /CE so they're not both drawing on the battery. maybe add a diode to bridge them so only is drawing? I'd strongly recommend reusing the hybrid-p...

expansion audio question: the rom i put on the board uses both nes and exp audio. the exp audio is very quiet- barely audible when tv volume is adjusted for normal nes audio volume. the donor board (kaiju monogatari, 111F0) appears to route exp audio from 163 to the cart edge directly, no components...

I've managed to get sram installed and play a game that makes use of it from eproms. both prg and chr use the nintendo-prg pinout. however, my AVS was not happy when the prg eprom /OE was connected to GND. I changed it so both /OE and /CE are on the /CE line, and it's working. for reference, wiring ...
