Thank you for posting :)

Built using retro transistor to transistor logic that allows a near arcade perfect version of After Burner to run on the Commodore 64.

My "After Burner II" demo running on a real Commodore 64 with hundreds of scaled sprites, sampled audio, RGB565 colour, and higher resolution. Using my Mega Wang 2000 Turbo Edition hardware. The SDK can be downloaded here: https://martin-piper.itch.io/bomb-jack-display-hardware/devl...

I plan to make the hardware available to purchase after one more hardware revision to optimise performance.

Good for him. It's obvious orange flump would cause a market slump.

8 data bits, write signal, reset address state logic. Each byte written will prime the 24 bit address to write to in the hardware and then store bytes with auto-incrementing address. This lets the C64, or any other machine capable of generating those signals, to write large amounts of memory to the hardware.

This is original :) It includes new functionality like multiple layers, layer priority, multiple palettes, scaled sprites, mode7, dithering, etc

I know, I was replying to the GP, whose definition of "original" this didn't fit (and that's fine, but, instead of complaining about it, they should build things).

Ahh:)

Thank you for posting. This is one of my projects. I was wondering why all the subscribers joined today.

What's the relation between this and MAME? I don't have the Bomb Jack arcade PCB (I've got others though) but I do have a Pi2JAMMA and, well, Bomb Jack using MAME.

Is this project something that could be replacing (partial?) hardware on a real Bomb Jack PCB (not unlike what some are doing with C64 chips, where new replacement can be dropped in place of old broken chips)?

It started off as a direct Bombjack arcade hardware replacement, it then grew way beyond what the arcade was capable of. MAME is software, this is hardware, no relation. :) Although interestingly the first version of the hardware did allow me to find a bug in the MAME implementation.

If someone sold RPI Pico back in 1980s when we were using 8-bit CPUs like 6502 then that would have been like supplying alien magic technology.

Oh this is one of my projects, thanks for the boost. :) This video goes into some more detail about how enhancements to Cucumber help to build more descriptive tests: https://www.youtube.com/watch?v=fdeVc2q6oB0&list=PLAAYJEX1Jb...

This engineer has a series where he carefully restores a Processor Technology SOL-20 Terminal Computer, the world's first true home computer (1976). The computer will go to the Dutch Home Computer Museum once restored.
