Thanks for taking the time to write that up. I reverse engineered this all from just the bits in the rom, and a lot of datasheet/patent archeology. Couldn't find the exact cpu fwiw. Did you compare with the Tengen code, ala 'rosetta' style? Otherwise I don't understand how you are gleaning informati...

All of this was figured out by segher, one of the few that hangs out on IRC. Did he reproduce this himself by looking at the IC chip, or is this just based on my circuit tracing here (and other circuit tracing comments in other threads)? http://nesdev.com/bbs/viewtopic.php?p=43119#43119 It sounds l...

What you described is essentially the 'Rosetta stone' approach which has been discussed before http://nesdev.com/bbs/viewtopic.php?t=5676 It is possible that we already have enough info to do this. So someone who is enjoys crytogram type puzzles, by all means give it a shot. ------ I've accidentally...

Mode 2 has an "offset per tile" ability.

That's the only thing I know of that can shift things vertically like that.

Chip decapping/dumping
Since there has been discussion of decapping/dumping here before (and I'm not sure the best place to ask), I'm hoping someone can give me a good lead. Basically, I am hoping to get the ROM dumped from an LCD controller chip. I've had bad luck finding companies that would do _any_ dumping at reasonab...

Re: Are CIC's universal?
Can I take the CIC from a PAL cart and just remove the current one on the copier to make it work natively on the PAL snes? Yes, that will work. Often the CIC chip on the copier is socketted just for this purpose. (The game doctors also have spots on the board to jumper it so the CIC signals are tak...

Did you read the links I posted? The questions are answered about the nature of the deal. Even probing equipment being used is mentioned. http://decap.mameworld.info/about-2/ No, I'm sorry I didn't. I saw mameworld and thought the decap page you listed was just this page: http://guru.mameworld.info...

TheGuru is secretive about his deal (or at least was last time I tried to ask him about it), so I'm not sure what all we can expect. (Unlike several images of metal layer masked rom he's shown, the DSP1 ROM cannot be read by merely decapping and imaging ... either staining or probing is necessary.) ...

I'm trying to make a SNES flash cart that can hold multiple games with SD card + (potentially) onboard DSP1 support. My first simplified prototype has run its course and I'm currently ordering prototypes of the full (hopefully final) version. I'm having fun and would like to share my work with other...
