I can't believe I'm still doing this. Anyway, it now has sound. Not perfect sound, but pitch-accurate sound at least, using ebitengine's excellent package 'oto'
https://github.com/ebitengine/oto

Accurate enough to identify a tune, possibly less accurate AY-3-8912 streaming, but I designed an audio manager with a proper pipeline, a ringbuffer and independent volume channels going into a mixer. That made replacing the audio backend quite straightforward. Sophisticated for this kind of project, perhaps unnecessary, but that was part of the fun too.

Ahhhhh glorious!

God save Jon Ritman! (and Bernie Drummond, wherever he is)

This reminds me I've made no effort whatsoever to plug the beeper or the Yamaha chip.

ZX Spectrum: emulated

To be honest, I thought it was going to be a lot harder, and it would take a lot of debugging to get this done.

But ultimately, I only had to grab parts of the older Spectrum emulator I had started last year, remove the old spaghetti Z80 that didn't work well, and plug the new well-tested zen80.

I would call this a very successful weekend

zen80 update: improved tests

*** Apart from the already substantial unit tests, we now have two additional and rather stringent tests:***

1. This test loads the ZX Spectrum 128 ROMs (0 and 1) and run that machine's initialisation process. Then it shows a statistical analysis of the instruction coverage that's been executed during rom initialisation. (total percentage of different opcodes executed for each instruction group)

2. The second big test implements traps as barebones CP/M shims, loads ZEXDOC.COM and runs its extensive stress test (this can be long).

Work is ongoing to support ZEXALL.COM as well, an even more stringent version of zexdoc that also tests undocumented registers and quirks of the Z80, one of the hardest tests known. This will be next, after I'm certain that this passes all ZEXDOC tests without a hitch. So far so good!

Calling #VintageComputing #RetroComputing and #Emulator developers/enthusiasts/and so forth. I'm writing a piece about a new hardware-generated test suite for the 286:
https://github.com/SingleStepTests/80286

and I'd love to include some comments. Will you use it, and if so how? Why has the 286 proven a challenge to emulate properly, and what else stands in the way of cycle-accurate emulation?

Can I overcome fate?

This is a screenshot from a video game. The player is looking at the stats of an opponent named Garland, who is level 6. Garland has 1731 HP, 336 CP, 161 BRV, 24 ATK, 17 DEF, and 13 LUK. He is equipped with an axe and bronze armor, giving him a bravery bonus of 3. The player can advance to the next screen by selecting the "NEXT" button.

Are you sad because some of Popc0rn/Nightfall's #snes trainers don't work under an #emulator ?

I was too, until I discovered that Nightfall's code stored trainer options in console copier SRAM even for ROM-only cartridge images - behavior an emulator would naturally prohibit.

To get your cheat on, patch the cartridge header to enable SRAM (7FD8: 00 -> 01).
