    HACHIBITTO - An MSX2 Fantasy Console

    I just released version 0.6 with speed improvements mostly for the DS-Lite and some other smaller accuracy improvements. I'm burnt out looking for this disk controller issue for games like Ys II. I've been all over the code - reworked most of it and even taken to just using fMSX method and...

    HACHIBITTO - An MSX2 Fantasy Console

    Thanks again, @esv_83 - I'll add it back to the list. I'm working through the Ys II issue which might be an FDC driver problem. Tricky and elusive. Maybe it will end up being the Xak 1 issue as well. Nothing in this stuff is easy :)

    HACHIBITTO - An MSX2 Fantasy Console

    Interesting stuff, @esv_83 - I think Xak1 is using Screen mode 7 or 8 and I know there is some issue with that and it's on my list of things to fix. Less sure about Vampire Killer ... I thought I had Screen Mode 5 working really well. I'll add it to the growing list! So much left to debug...

    HACHIBITTO - An MSX2 Fantasy Console

    Version 0.4 release. Massive update under the hood. Sound clicks mid-game are largely gone now with a new smoothing filter (still one good click as you start the emulation but not during gameplay) - SCC games are sounding really good. It comes at a cost - I had to add light frameskip to the...

    HACHIBITTO - An MSX2 Fantasy Console

    Version 0.3 released. Fixed the memory backing so a real 128K machine is now emulated (many .DSK games would fail as it was only 64K of RAM despite what the MSX logo screen was saying). Fixed Screen 8 so high color bitmaps look correct. Key X and Y are now configurable but default to screen PAN...

    HACHIBITTO - An MSX2 Fantasy Console

    Awesome @radicalten !! Just checked in version 0.2 with a re-write of the FDC to support MSX2 games (and fix MSX1 games with the MSX2 bios). Not every disk game will run - but many will. You can swap disks in the MSX mini0menu but I just added that a few minutes ago and so use with caution :)...

    HACHIBITTO - An MSX2 Fantasy Console

    Version 0.1 is uploaded. No idea if it works on a DS-Lite. Heck, not even sure if it works on a DSi :) But go play some Firebird and Lily's Saga. You can report bugs if you want, but at this early stage, I probably won't care. https://github.com/wavemotion-dave/Hachibitto No BIOS needed -...

    HACHIBITTO - An MSX2 Fantasy Console

    No reason this needs to exist other than I tried to shovel a sort of makeshift MSX2 support into ColecoDS and found myself 50 hours later having really torn apart the codebase to rebuild it for MSX2 support with the VDP9938 Video Display Processor. What a pain in the ass... a total waste of...

    Homebrew A5200DS - Improved

    So A8DS will play 5200 carts though it’s not custom tailored to it. I keep the 5200 separate because it’s always the red-headed stepchild of the larger A8 scene and the system deserves better. Sane reason I keep the MC10 MicroDS separate from DracoDS.

    ColecoDS - Improved

    https://github.com/wavemotion-dave/ColecoDS V11.0: 20-Aug-2026 by wavemotion-dave Added preliminary handling of undocumented flags X and Y for improved CPU accuracy. Fix for 64K 'Activision PCB' banking so that we correctly start the ROM running. Other minor cleanups and commenting as time...

    GimliDS

    That’s cool! I can certainly look into mouse support via the touch screen. I don’t think it would be too much trouble given that the X and Y positions are simply read from the SID chip which handles the interface. I’ll add it to the TO-DO list.

    Draco-DS - A Dragon / Tandy CoCo Emulator

    Okay... was back trying to debug the sound in Shamus and ended up re-working the sound driver. It didn't help Shamus but it's a big improvement in accuracy and now games like Demon Attack have proper sounds! I checked in a daily 1.6b build on my github site... still trying to figure out Shamus...

    Micro-DS ... a Tandy MC-10 Micro Color Computer Emulator

    Well... it's been a minute as the kids say! Almost a year since my initial release of MicroDS - a handheld MC-10 (and Alice) emulator running on a DS/DSi/XL/LL. https://github.com/wavemotion-dave/MicroDS Not a lot changed with version 1.1... I've added 60Hz 'true-sync' that synchronizes the...

    Draco-DS - A Dragon / Tandy CoCo Emulator

    https://github.com/wavemotion-dave/DracoDS V1.6: 05-Aug-2026 by wavemotion-dave Improved accuracy on PIA handling (DDR and masking supported) - sound and keyboard reading more robust. More games read keys/joystick more correctly. Massively improved .DSK and .CAS type detection and loading. Use...

    https://github.com/wavemotion-dave/SpeccySE Version 2.1 - 30-July-2026 by wavemotion-dave Optimization pass on beeper driver so games sound a bit more authentic with fewer buffer drops. Optimization pass on CPU and ULA driver to eek out another 3% speed. Pressing START/SELECT will stop tape...
