The Mega Multi is finally about to start appearing with retailers. Sorry for the delay, they've been ready to go for a while, but with one thing and another kept getting delayed.

Support for Atari ST, Atari XL/XE, Amiga, CD32 (7 button), C64, VIC20 and Spectrum (Kemptson…

I wanted a super-simple USB dev cart for the ST so I can play around with code very quickly on real hardware. So here it is! 😀

Inspired to get this done by all the cool stuff coming from @RetroRacing and @keithclarkcouk. The plan is remote reset and fast code upload over USB.…

This is great! For those who remember cool and bizarre home made hardware from their youth that you built from a magazine, this is a fantastic re-visit. Well worth a watch and a great way to get into electronics. Make something simple that works!
@TheRetroHQ Thanks to Jelly load, you can relive those halcyon days and start to download programs slowly from YouTube.

Holy cow, watching TV programs and reading magazines from the 1980's is so refreshing! They encourage you to build things out of electronic components, type in your own programs and participate in actual technological advances! No wonder it bred a generation of techies. 😁

Argonaut is a legandary name in the industry, I was massively lucky for it to be my first job and it's fantastic to see the head of the multi-coloured Argonaut again. Can't wait to see more come out of this. Congratulations all involved! 😄
Thank you, everyone.

An arcade joystick I made from an old JAMMA cab control panel about 25 years ago has now been re-wired for super-gun use! Much easier than poking wires into connector blocks. 👍

Some more improvements on the Jaguar voxel engine and a quick video! Doing stuff like this is my equivalent of giving my brain a holiday. 😆

With lower quality settings it achieves a pretty consistent 50fps. Voxel resolution is 160x200 rendered to a 320x200 image.

The voxel map…

A bit of optimisation by using the blitter to do the height map traversal and store it locally for the GPU to iterate linearly has given a good speed up, now getting a good 25fps at an acceptable visual quality. A bit chunky, but good for the era!

A quick rest from doing useful things, a voxelspace gpu renderer for the Jaguar! As voxels seem to be all the rage. GPU only rendering, no blitter, 160x200 running at 15fps.

For those of you who have a Jaguar GD and are looking for something new, why not support the awesome Reboot Games who are continuing to support the Jaguar even today!

Head on over and see if anything takes your fancy:
Updated the Jaguar port of Operation: Thunderbolt.... continues now work!

There's another JagGD firmware update for people to grab. It should help again with CD stability and fixes some issues with memory track on homebrew (notably Yopaz and Alice).
Usual disclaimer applies: it's still not perfect and is unlikely to ever be, but it's improving.

Not of interest to many, but I’m pleased with myself. 😆 My New Years resolution — half trail marathon this year. Going well, 10 miles trail running with 1000ft of climbs today. Furthest I’ve run. And with my trusty canine companion! Always nice to have company…

Pace was a bit…

Absolutely insane project, I love it! Great to see the progress.
Much improved reliability, booting every time now (except for a mysterious reset issue) and missing sound is restored! Video slightly improved but still washed out and vicious banding. Good enough to start working on the 32X side.

I’m feeling knackered and ill so I decided to do something fun. I’ve built up a T20 DVI out test board I designed ages ago and I’m pleasantly surprised I can output 720p directly from the LVDS outputs via a PTN3366.

Ahhh, I'm definitely getting into the 'adding too much' phase of testing and bug fixing for the MegaMulti. I've now gone and added a Mega7800 mode so you can use the Mega7800 multi-button features as well. 😬

As I'm doing a general multi-system version of the Mega7800 for Atari style joystick pinouts, I guess I should do a MegaMSX as well?

Now working in compatible (single fire button) mode with the ability to add B as up for games which use up to jump.

Also has 2-3 button modes with active high (C64) and low (some C64, Amiga and Kempston). Atari 8bits could also use this, not sure if any games do though?
I did a quick new layout for the MegaMulti, which is to be a multi-platform version of the Mega7800.

It will support Amiga, CD32, Atari ST, C64 and Spectrum (Kempston). Amiga and C64 will also support light guns.

No Amstrad CPC unfortunately, as it's a bit weird. 🙄

I just tested this, and it explains an odd thing I remember as a kid. Sometimes the ST would just keyclick like mad when you booted and the keyboard wouldn't work. Yeah, guess what, this is because the keyboard controller was not running due to the fire button being held down! 😂
According to the data sheet, if you hold down mouse or fire buttons when you switch the ST on, the keyboard should not function as the ikbd will be in an external memory mode. This cannot be the case, surely? I don’t have an ST handy to try currently… 🤔
