Nah, a CRC checker was implemented in order to find the right table to use for each BIOS :P
You'll need to use the same logic in UniROM in order to achieve perfect boot compatibility.

Hi everyone. I got Xplorer FX cartridge, burned the CD but unfortunately flashing UNIROM stucked and now my cartridge is not working at all. The white PS1 boot screen doesn't show up if the cartridge is plugged into parallel port of the console. I get only black screen. How can I bring this cartridge back to life? Please advice something

Burn the good old X-Flash CD and it will re-flash your Xplorers EEPROM to whatever binary you'd like (a few are already included in the image to get you off the ground).

I tried other methods I can't get xplorer, action replay codes etc... To work properly however level select on crash bandicoot worked fine but causes major lagging and graphical glitches etc... Anyone have a way to get cheat codes to work fine?

Issue: Unirom + Caetla combo on a standard xplorer with switch set to 'on' position = Caetla does not recognise the cdr as a game so you cannot start it at all. It just hangs on the loading screen when you try.

Explanation: With some testing i found that for some reason from cold boot caetla will detect the game cdr as a music cdr (e.g hogs of war ntsc USA). This is verified because when I try to force the game executable (slus/sles/sces etc.) from the inbuilt cd viewer it comes up with a music player. Pressing x to back out and re enter the cd viewer doesn't change anything. However, when caetla does recognise the cdr as a game disc entering the cd explorer in caetla brings up the game directory and you can start the game from the executable. I can also start the game with/wo cheats as expected in this second situation.

Btw - when I had switch set to off position then the same thing was happening and sometimes unirom wasn't intercepting the boot sequence and the ps1 internal music player was launching (e.g castlevania sotn ntsc j)

Sometimes when I cold boot I just get a black screen (ie no unirom/caetla no normal playstation boot either)

Hi All, unfortunately im seeing the behavior that Kukuruzo is seeing due to a bad flash. I dont have a chipped console but i do have a blue debugger unit but im seeing the black screen if the (in my case gameshark) is plugged into the console at all. i've also tried booting the x-flash cd and then connecting the cart after the fact, but the screen goes black as soon as the cart is connected. is the cart bricked?

Have you tried changing the switch position on the cartridge? All-in-all, you should be able to boot X-Flash without the cartridge in on your debugger, plug in the cartridge and press R1 and then R2 enable comms and force a detection of the cartridge. From there you can flash CAETLA 0.34 and then retry again afterwards flashing UniROM.

It's very strange. It shouldn't make the screen go blank, and if it is, it's throwing junk on the bus when it's plugged in (unless somehow it's shorted and holding the PSX in 'reset', or the reset line is being held low since there is a reset line on the parallel port). I'd try taking the Game Shark apart and lifting the chip select pin and shorting it to ground (or VCC depending on the EEPROM's specifications). That way, the cartridge is on the bus, but the chip is disabled. Then, when X-Flash has booted, re-enable chip select. Otherwise, the EEPROM will need to be manually reset using an EEPROM programmer.

@Shadow, ive tried on the device on both switch positions with no luck there. I'm not sure its a hardware short because pre-flash it was working fine as a standard cheat device. I'm not exactly handy when it comes to manipulating connections at that level (lifting pins, etc). but ive tried your first option:
-boot xflash on debugger
-plug cart into debugger
-screen immediately goes black when plugged in (appears softlock)
-console stays in softlock even after cart is removed. remains until full reboot

btw if it makes a difference i was trying to flash unirom+catelantsc onto a 256kb chip

hey guys, after a little help if possible, iv got a game hunter lite cd version card v8.0 uk version (no parallel port)

Image

for my non chipped ps1-SCPH-5502. The card boots up works fine for cheats, but will not play backups, which was why i originally bought it, spotted this software, but im struggling with how to get it to boot the unirom image from a cd, burned the bin/cue to a cd at slowest speeds, and iv tried multiple things to get it to boot the disc, tried with the instructions provided by someone on the previous page, but this didnt help me unfortunately.

This is the menu i get when its booted to the card if it helps

Image

Just wondering if anyone could point me in the right direction

To boot UniROM, you'll have to do the disc swap trick.

It'd be the cartridge. You can try flashing it anyway, but it might fail and brick it. Your choice.

is it normal for the unirom burnt disc to spin the opposite way to the original game disc?

Uhhhhh the what now? Sounds like the polarity is messed up on the motor that spins the disc for some reason. So you're regular games are working just fine? If so, I'm dumbfounded as to why the polarity would flip the other way with only that disc.... never heard of such a thing

All i get is "loading, hang on," for any disk... for hours... disc spinning. Ugh, I only had one Gold Finger cart; I can't believe I fell for this. PLEASE, can anyone tell me if it's possible to revert my cart to the original state, so I can play backups again??

You'll have to burn to the disc though a dump of the Gold Finger ROM you had.

If not, I have about 100 brand new Gold Finger cartridges, so if you'd like one, just let me know :P

Hi,

I have a SPCH-7502 PAL PS1.

It's possible to boot the Bios with NoCash Patched ? And How ?

Thanks.
