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:

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.

Rather exciting, some long unseen Atari gerbers are being recovered! Falcon040?!

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.

I now have a way to test MSX joystick compatibility!

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.

Jetpac with the MegaMulti is good! B for thrust makes it a lot more enjoyable to play. #retrogaming

New 7800GD firmware released!

Firmware 23.12.0639
Added a few more games to the break warning list
Fixed instability issues with serial debugging

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?

A composite modded spectrum plus before 10am? I’ve over achieved already today!

3 button joystick input from a megadrive controller on a C64? Sure! Why not, eh? Made possible by the MegaMulti.

7800GD firmware update released!

Firmware 23.11.2863
Added support for 2600 EF mapper (Zippy the Porcupine)
Added auto-fix for bad headers for known ROMs

This is the first use I’ve had for stripboard in years. It’s awesome! Super joyport sniffer.

7800GD Firmware Update 23.11.0741
Fixed an issue where the POKEY was out of tune under certain circumstances. Noticeable in the title music for E.X.O.

Made some time over the weekend to add a coat or four of paint, starting to look nice!

Made a start on the case! Looks awesome.

Starting some Christmas present manufacture… Gotta love the nixie glow!

Some MegaMulti prototype controller adapters made up and ready to send out. It’s nice to work on something which doesn’t take multiple years to get to this point!

Skeet Shooting on the Amiga with a MegaMulti and Sega light phaser.

Hopefully this is visible, but that’s the CD32 pad reading working for the MegaMulti. Standard 1-3 button joystick also work well.

I’ve never used one of these things before in my life. Should be fun! Wish me luck…

I’ve packed my greasy weazle into an Iomega external CDRW drive case, reusing the rear panel connectors and PSU. A very tidy, and cheap, solution for casing a greaseweazle setup!

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 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!

Upcoming retro computer event in Nottingham. Looks interesting!

Hello there ! We've just released a new version of the first #MarioBros game on #Amstrad #CPC . Enjoy ! #retrogames #pixelart #SuperMarioBros

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.
