I’m currently working on Naomi again. I’ve fixed various CRTC registers (hence now the test mode looks fine at 640×240 + pixel double) and hblank irq firing. The latter presumably makes Jingy Storm to work again (actually a regression because it was booting before the textures were added):

I was also checking The Typing of the Dead and surprisingly it was putting a string that wasn’t present before. After adding a missing mirror, it now looks like this:

I’m currently improving again stuff in the Super NES driver. Right now, I have a major task to do: implement the master cycle “steals” that the devices does on that HW. Starting by the simplest one (the DMA) it starts to give reasonable results, The Smurfs – Travel the World, Mario Paint, Pachio Kun Special 2 and Super Cup Soccer all boots and Libble Rabble, Major Title and Super Tetris 2 + Bombliss have working inputs. Probably something regressed for now, but we’ll do death count once that all of this is correctly implemented …

Iq_132 of FBA fame pointed me that the right colors in Uncle Poo title screen can be found at color offsets 0x08-0x0f … after some further investigations I’ve found that there’s a 2-bit pal banking tied to the 0xb700 port. So, the tilemap has 8 independent color offset + two pal banks that allow it to select the whole 0x20 color offsets.

Speaking of pal banks, I’ve found it in Three Dealers Casino House, that gives a slight improvement for the 2$ dealer girl / 5$ dealer man color skin:

Last but not least, fixed for good trasparency issues in this game, after some exaustive dasm tracking that only indicated that the HW can do trasparency in any case if the pen has a value of 0:

Currently looking (again) at the Multi Amenity Cassette System, a Japanese Arcade System developed by I’Max in 1995. First off, I’ve removed the existing hacks in the driver and implemented BIOS support and basic BIOS/cart ROM bankswitch.

First effect of this is improved logic in Kisekae Mahjong, that boots, runs some attract mode and it’s playable until it resets in the middle of the gameplay (still investigating on it):

Team Europe and the Dumping Union proudly presents … Uncle Poo, an obscure 1983 game from the even more obscure Diatec, possibly a bootleg/hack of something else obscure that we don’t know jack about it either. Me and Haze worked on the driver for this, it currently works apart from sound and a bunch of minor bits. I also don’t know why the title screen colors looks so awkward, but I don’t see anything weird from the ROM-to-videoram transfer so I don’t know if it’s the correct behaviour or not…

As you can see, game is a maze game with scrolling (from left to right), on which you have to collect money/diamonds in order to advance to the next level. Your main attack is a … er, a fart (yeah, not joking here, check last snap), it’s used for breaking objects and kill enemies. There is also another button, the character puts blades on his feet and moves faster, but it costs a lot of  “power points” (also used by the farting).

I think it’s not a bad game per-se, it’s at least original in game design (for a 1983 game, obviously). If it rings a bell to anybody about what it could truly be let us know, thanks.
