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 »
So I just had a friend of a friend find Shin Megami Tensei – Devil Children: Aka no Sho Rev A in Japan. Upon analyzing the changes made and compared them to the following game in the series, Shiro no Sho, it’s kind of safe to say that there is… Read more »
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 recently acquired more Sachen games, among them are 31B-001 (Taiwanese version), 16B-002 (2x 8B with switch), the elusive 6B-001, which I guess is now confirmed to exist and an unknown 16B variant featuring the Mahjong titles and a wide selection of other titles, meaning it’s not just two… Read more »
Just wanted to let everybody know that finally, all Sachen 4 in 1 Mono games were dumped and put into DoM by yours truly. I would like to point out that taizou and BigFred lent a hand in letting me borrow their games.
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 »
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 »
Next week… Now you know how that worked out… Anyway, I was recently contacted on no-intro about an update on the Sachen dumps. And I thought why not share my current progress with the rest of the world 🙂 So, currently dumped physical media: 1B: — 001 – Beast Fighter… Read more »
So it’s been a while. akubi sent me some of her games that contain interesting PCBs — the most outstanding being DMG-Z01-01 followed by DMG-KECN-SP. Still no idea why they put an extra transistor on the latter tho… The former has some weird ROM where Sharp combined 2x 16Mbit in… Read more »
So thanks to BigFred from no-intro, I got my hands on more Sachen cartridges. A few were mono cartridges, which I managed to dump using my 4B-007 code. Unlocking color cartridges, which are compatible with CGB as well as DMG works just fine in DMG mode. However, the internal mechanics… Read more »
