      Comments Off on MMM01 documentation up

I just put up a more readable MMM01 documentation on my wiki, check it out. While I implemented the mapper already in MESS, I found some small issues with it that I’ll send a pull request over soon. If you have any idea what the unknown bit might be there… Read more »

Heya, I’m not dead :D

Hey, so a lot has happened recently. First off, I moved cities for a new job and that’s why my coverage has been spotty to say the least. Unfortunately, I’ll only really get settled November-ish, maybe a bit sooner. What did I do since February you ask? Well, I looked… Read more »

So I noticed I neglected to update DoM with the mono 4B games I had already dumped. I did so now. All redumps are in as well as new entries for 4B-001, 4B-004, 4B-006, 4B-008. I updated the last Sachen post as well. Maybe a bit more info on color… Read more »

Small Sachen Update

      Comments Off on Small Sachen Update

So I received more Sachen carts in the mail today and finally confirmed that Sachen’s MMC1 also has 8 high address lines, as could be guessed from the zero-adjustment being performed on all 8 data bits. Probably now going to change the dumper to read RB 0x00 from 0x4000-0x7FFF by… Read more »
