Re: SuperDisc BIOS released + analysis [attn: nocash]

Just wanted to take a minute and thank you guys for the effort you put into this so far, especially byuu and nocash of course! Finally getting a long-standing mystery like that revealed feels really satisfying. Also congratulations for writing the first homebrew software for it, nocash! I'm kind of ...

Re: Super Road Blaster SNES Cart - Feasible?

I've thought about this before. Another (IMHO the most feasible) solution would be to rewrite the game (source code available here: https://github.com/DocSchoko/SNES-SuperRoadBlaster ) to run on stock hardware with minimal additional custom hardware: -replace MSU-1 audio with BRR streaming via HDMA....

I'll just leave this here:
The goal of this device is to give the SNES stand-alone networking capabilities and enable online multiplayer support, not establish connection with or by means of a local desktop computer.

Re: Castle Platformer - would like feedback

I usually don't comment on here anymore, but this is great! Your code is concise, highly readable and well-structured, just beautiful. As for the gameplay, I think the physics of version 2 are almost fine. It still feels like it is a bit on the floaty and "running-on-rails" side, but that may be cau...

I've released the finished game earlier this week.
Enjoy & check it out at http://www.dforce3000.de/?uid=43.

FYI, the game runs perfectly fine in NTSC and PAL mode now.

Dumping the charset would be nice.
I saw a pin labeled test in one of the datasheets.
Surely there's some way to dump/verify the ROM.
No idea if it's worth the effort, though.

If everything else fails, we could resort to hacking KROM1 to display all chars at once and take a picture of that...

The major missing detail is the part number of the OSD video controller (should be the huge 28pin SMD chip in rear section of mainboard). The thing is apparently accessed via the HD640's CSI/O serial port, the software seems to be writing character numbers, screen coordinates, and maybe color attri...

Super Famicom Box KROM1 Great, that'll be interesting! At first glance, it seems to be actually Z80 code (or if my guess was correct, HD64180 code; ie. extended Z80). Do you still have the box disassembled? The part number of the 80pin (or so) chip would be interesting (somewhere in rear right), an...

Great work, and thanks for furthering research on some of the more obscure devices!
Especially the Satellaview and Super Famicom Box sections are greatly appreciated!

The cartridge lockout (CIC) and system video mode is completely independant of the ROM, so any ROM works and runs on a PAL system in 50 Hz theoretically, albeit a little bit slower. However, there are two problems you may encounter: 1) the game may detect the current video mode and refuse to run if ...

Send it to Guru and have the ROMs themselves read out directly. Then if needed, send the image to d4s to crack any stupid protection checks. Note: either of them may be busy or not want to do this and say no. Can do. I haven't delved too deeply into the hardware. Shouldn't be too complicated, thoug...
