Title: Question for people with an SGX/PCE...
Post by: Tom on June 19, 2009, 10:04:19 AM

And a Super CDROM^2 attached to it. And... a tototek card. If anyone could test to see of a rom flashed to the card in that setup can access save ram/games/data (BRAM) without problems, it would be much appreciated.  8)

Actually, if you have a PCE+SuperCDROM^2+tototek card. That would work too.

I have a Coregrafx+SuperCDROM+Tototek card, and it appears to erase BRAM every time I use it, and make it not appear to exist, sometimes.

Are you having the same problem?

Perhaps its "mapper" functions use similar areas to BRAM.  Why not take a look inside the menu program?

Chris yes. That exact problem. I connected my white PCE to the Super CDROM^2 and it still does it. Looks like it's some where problem with Super CDROM^2 and tototek card. Works fine with my US Duo.

 I wrote some code to take advantage of the 64k base CD memory. Which I also couldn't access on the Super CDROM^2 setup. Looks like a bus conflict caused be something/logic on the card.
