https://github.com/agranlund/raven/rele ... A1.latest

Lastest package is mostly behind the scenes, bugfixing and chasing cache related stuff.
Integration of a separate isa_bios wip refactoring branch to main.
GCC programs are now compiled with 15.2.0-mintelf instead of 13.4.0-mint.

These may depend on each other being similarly recent so update all of them: rom, rvbios, isa_bios, rvsnd
(and for rvsnd update the entire folder as the new exe is not backwards compatible with the older driver files)

Additionally:
- Latest MiNT 1.19 release has support for Raven hardware poweroff (*)
- A pull request for the same feature in MagiC has been submitted so should hopefully end up in releases there too.

(*) Hardware poweroff requires CKBD controller, as well as soldering one wire mentioned here:
https://github.com/agranlund/raven/tree ... ades/ckbd

Code: Select all

260406:

rom (bios)
faster vgabios x86emu
export function for moving 060sp to any vector table
d and a commands can now take register as parameter

rom (emutos)
updated to #f96a524 @ 20260331
correct cache status when emudesk.inf is not present
removed cache menu item (as Falcon, use control panel if needed)

rvbios:
move 060sp to TOS vectors (fix Mint 1.16.0 crash)
support older CT60 xbios calls (fix xcontrol for CT60 crash)
support puntaes xbios call (MagiC poweroff)

isa_bios:
more flexible device config options (isa_bios.inf)
more useful device info log (isa_bios.log)

rvsound:
fix cache related crash, should now be copyback safe.
(update entire folder, including drivers)

software:
added xcontrol.acc (CT60 patched version)
added general.cpx (CT60 patched version)
added gsxbmixer (compatible with rvsnd)

Great work!

Did you see, as of the latest release, PiGUS now emulates a Soundblaster16 also!

I will need to check my build for the Raven PicoGUS PGUSINIT to add the updates for the new firmware to use the new features.

This has only been tested in STEEM emulator without access to a PicoGUS. Consider this untested for anyone wanting to try this with the new PicoGUS v4.0.0 firmware. Also, totally untested with the latest Raven updates. I am away from my Raven/PicoGUS at the moment so unable to test it. :)

I think I also made changes in the previous PGUSINIT version to get the firmware updating working. I have not checked this is this new version yet so may not work.

This PGUSINIT.PRG v3.8.0a includes the modifications for the /flash firmware updates pulled from the previous version.

Again, not yet tested so your milage may vary when using it. Feedback is welcomed from anyone testing it.

After the last update I have video artifacts and crashes in games (Doom etc). :|

Keeping the new rom and using the previous Raven distribution works well.

All right. Everything works with the new update.
It is Picogus firmware 4.0.0.
Reset 3.2.1 and everything is ok.
