That's now all the original commercial games running on the 7800GD on NTSC, including built-in POKEY support! I am aiming for dual POKEY and YM2151 support for final release.

7800 GameDrive direct mapped, SuperGame banked and Activision banked games now supported and working. A few crashing, but largely working now. A few more mappers to get through then onto POKEY.

BIOS is now fully booting into games on #MiSTerFPGA PlayStation core with the latest fix. No more forced fastboot. This also fixes some games, e.g. Glover is now playable.

7800 GameDrive coming on nicely! Basic mappers and game selection working. Moving onto banked mappers. 👌

I was having issues getting a stable clock from Maria as it's so noisy it actually glitches the main clock. This is evident on some Maria chips with a wavy image. I'm now driving the main system clock into Maria (nice bodge below!) and am getting a stable image on 3 chips! 1/2

October 25th 2021, 20:35:40

Finally something approaching stable. Different Maria chips in different states (cold / warm) give slightly different results, so more tweaking required, but a big improvement! Nearly there..,

Amazing how small an ARM1 was in terms of transistors, due to its RISC architecture. The 68000 being 68k transistors by comparison. I like the CISC instruction set so much more, though, it’s like someone took C operators and made them mnemonics. Which is, I guess, what happened!
how it started: how it’s going:

It's quite an honor to see my products among those of @krikzz and @terraonion. Certainly not something I thought would be a thing a few years ago. 😄

Wow, that’s insane! Congratulations all involved. 😄
Selling 3000 copies of a new #C64 game in these days is unprecedented. But when you have a game as great as Sam's Journey then the impossible can happen! If you have yet to experience one of the greatest games on the C64 then head over to

Finally getting *somewhere* with the 7800RGB. The video output from Maria is so jittery I've actually given up trying to use it and have instead done Maria's job for her and assembled each scanline from the display lists being read in!

That is nice! The CPC can do some really nice graphics if the palette is used to its best.

For coders out there, the first commit of the Jaguar GameDrive homebrew API is available.



This allows you to use functionality of the GD cart in your own code. Firmware compatible with it will be out next week, just going through final testing. 😄

Very nice! Soon people will be able to easily and freely use the Jag GD functionality in their own code. 😄
RAPTOR GD Functions coming along nicely :)

Some stuff for both myself and @TheRetroHQ still to work through, but looking good so far!

Nice work, SainT 🙂

A2560 Foenix U - The MC68SEC000 @20Mhz new retro computer. Early test & FPGA debugging. It boots now and runs small code. A bit more FPGA code implementation to do, but will soon be ready to be put into the Kernel Master... So, it will ship really soon!

The new 7800RGB board is behaving better, the last one had some odd tearing issues.

There are still issues, but hopefully they'll be resolvable.

7800 video generation is VERY jittery. The white bar represents 908 cycle lines, this SHOULD be straight. MARIA is dropping cycles!

September 23rd 2021, 09:03:31

A new firmware for the JagGD is coming shortly! We're in final testing now.

This is mostly for homebrew folks, adding an API for the GD features and allowing ROM's to be locked to individual carts or memory cards should people want to do this.

More details soon. 😄

Second stab at the Atari 7800 RGB project. Although I forgot to order the needed DIP sockets and headers I need, so it will be a few days until I can build one!

i'm happy to announce the release of my latest project, the Graphics Gremlin! it is an 8-bit retro video card for ISA bus computers, and it emulates the MDA and CGA graphics cards. scan conversion is built in so it works with modern LCD monitors!😈

This has to be the most awesomely pointless, yet completely awesome thing I have ever seen!

This proves without a doubt that there needs to be a modern alternative for every retro peripheral ever made. 😄

After a bit of fiddling the 7800 RGB luma only output is rock solid and perfectly crisp. I need to see if I can bodge a PLL on there to get the chroma sampling clock.

I've released the source code of my previous ZX Spectrum game: Castaway.

It isn't great, but it may be an interesting read to some people. I don't know.
