Graphics are low priority at my list, as that lcd is main display in this project.
Top priority now is to get that software boot from cartridge. With using runrom or exe2rom i can make rom that works, BUT it needs bootdisc (any official blackdisc) to start.
I also have some sources of booting cartridge, but they are in asm and i have no idea how to use that in my c-source.
So how do i get my software boot from cartridge similar way as Caetla? Power-on and it's running without any bootlogos.

Not sure. You will just have to use the bootdisc method for now

It will do You don't need to use an Xplorer though - any fake cartridge flashed with it will work so you can make a dedicated system.

Yep, that's why i got some old GameSharks.
But someday i will make that boot work properly, even if i have to write whole damn thing in asm (too bad i don't know much asm)

Commander's New Brain, MSP430G2452.
Buttonboard from some old crt-display, to control cd-player.
It appears that you have sector problems. This is caused from mastering a PSX CD-ROM incorrectly.
If you need help knowing how to master it correctly, just let me know and I'll get that guide written and hopefully moved to the help section.

Booting from cartridge without bootdisc.
Some delay at start (spuinit, cdinit or something..).
Thanks to sicklebrick for new romloader!

Sicklebrick needs add this assembly into his build.
It should bypass the BIOS boot sequence and just load what is needed.

Hah, awesome!
Cheers Shadow - I'll get to work figuring that out!
Where did you disassemble it from btw?

I've had this file for a while now as a well known PSX scener sent it to me.
It was disassembled from CAETLA I beleive

Cool, very helpful - thanks
Only took a bit of patching (register names, explicitly loading the jump table), but it boots perfectly now! I initially thought it was something SPU relted as some demos like Sadtro would still run but lag like the SPU was causing some kinda blocking. I suppose it's possible to figure that out now though.
