UniROM 8.0.K - GDB Debugging, install/backup to/from memory card, homebrew from memcard, etc

[Mdv]

the latest version of unirom 8.0.E has a feature where you can recover deleted game saves on the memory card

[mistamontiel]

Interesting that PAL version Yusha Heaven's Gate just works! SLES-00713

Is there a list somewhere about what roms and their variants are on the Unirom-discs and what flashsize they require?

unirom is flashed to 128kb cartridges

I don't have such list on hand but you can simply load Unirom's iso with an emulator such as DuckStation and check available roms/sizes from the "Install Unirom -> Restore Cart from CD" menu.

Alright, thanks.

Got vE now, Baby Universe runs but skippy tracks and then even the Playstation Developer DIsc working

But Heaven's Gate SLPS-00667 now does not even try hangs on green screen UniROM

Thanks, I'll take a look at Heaven's Gate.
What model are you on? (ping me on discord if it's easier, cheers)

[mistamontiel]

Cheers dog! Again even tonyhax can't do Heaven's Gate but the PAL variant just works! Not a amazing title either, I did see it through already

SCPH 7501 is mine? The last model with parallel port

Hi. I tried to download the source code for unirom from your github but its not available. can you send it to me? many thanks

[Octane]

I can't get either the Japanese nor PAL versions of Bishi Bashi Special to run, and it's the only game I've encountered that doesn't boot.

Thanks for letting me know

Nice mix of devloper-focused features and quality of life stuff.
Aside from Elf and PCDrv support, there's some nice compatibility fixes, and an updated rom set from Squaresoft74

As always, thanks to everyone who contributed

The FreePSXBoot images on the disc can now be installed to memcard #2 and left in the drive while you boot

Lemme know if it's working for you now!

Likewise!

What was bad about Crisis Beat? I played that one through infinite respawns, PAL

Villain and the ender was such lacking all I recall

Could SetSession be added to the disc swap method? It would make it work with CDDA and large games without having to have a legit disc with a big enough TOC.

EZ-Swap allows reading and booting CD-Rs by allowing a swap trick to be performed easily, as it stops the disc during the swap procedure to allow for swapping without the risk of damaging the disc or console. As of 0.28b, games and homebrew that use CD Audio will work properly by issuing a SetSession command to reload the ToC without clearing the authentication state, though accessing newer sessions in a multi-session disc is not possible. Obviously, an official copy of a game that matches the console's region is required for this procedure. This option may seem redundant as Uunlock is the better overall option, but this is here for Japan region consoles which do not support Unlock.

Unfortunately, still just a black screen at boot.

I've noticed that I couldn't write a FreePsxBoot memcard while using a wireless Logitech controller. When I had to press X to write the memory card I couldn't because the receiver wasn't accepting the controller signal anymore and even reconnecting it wouldn't change anything. I had to use a cable controller. Tteid this more than once.
Probably that's normal and it's supposed to be that way and there's something that somehow "disable" the receiver.
Maybe you already knew that but I posted it cause it happened to me recently.

BTW, what does the PSX serial hardware do as far as logic, protocol, voltage levels... is it a RS232 implementation?

Set your chip to 3.3 and you're good to go.
In terms of actual setup (stop bits, etc) I'd say go take a look at the NoPS source:

Thanks! I got some more serial adapters / chips to try. I got busy, but maybe soon.

Hello, today I tried to softmode my PS1 with uniroom. I successfully patched my cheatcard. But after that every copied CD i'm trying to load leads to error:
Not a valid CD or Device is Locked!
Even the CD I used to flash my cheatcard is unreadable now. Original CD i used for swap works fine.
Do you have any ideas why is that?
MY PS1 is SCPH-5500
Status screen shows this:
Booted from ROM: 1
With Caetla: 0
CD Unlocked: 0
Boot from MC: 0

Can someone show me the direction to dig in my problem, Is it my blank CD's, my PS CD drive, or a flash cart...
Thanks in advance!
