Caetla stuck in japanese language

[Thelows]

Installed unirom + caetla on a gameshark pro cart. Psx is a 5501. Caetla is displayed in japanese. When I go the the language setting in caetla and switch it to English nothing happens after pressing "O" pressing x just brings me to the previous screen and there is no "apply" button.

Can you give the EEPROM specs from the status screen ?

Can you check that the chip is really a SST 28SF040 by opening the cart ? If you don't know what to look at, you can upload pics of the inside here?

You might have a chip that needs 12V to program, hence the settings not being remembered.

Hey, 12V is highly unlikely, given that most users will have installed Unirom using a PSX flasher software (often the Uni bootdisk itself). I haven't experienced this particular problem myself though, so sorry, can't help there.

Hey, you familiar with a hex editor? What you can do is open the rom file from the unirom CD (unirom_withcaetla.rom I think for this model)

Then change byte 0x0001BF97 with a hex editor from 0x00 to 0x01 And burn that back onto a blank disk

(It can be an empty disc with just that file on it, Mode 2 XA preferablly)

The unirom file explorer will then let you flash that file, pre-set to english.

Failing that, tell me which CD version you're using and I'll do the patch :)

[Thelows]

Thank you guys! I'll see if I can do it myself. I'll let you know. I checked the Unirom 8.0.K image and I only see "UNIROM_S.ROM" and "UNIROM_W.ROM" Im assuming the "unirom-w.rom" is the one I want to edit?

[Thelows]

I used HxD to open "unirom_w.rom" and I cannot find the byte string 0x0001BF97. Im probably just doing it wrong. you mentioned patching it?

[ramapcsx2]

He probably means the byte at offset 0x0001BF97 :)

Edit: However, when I open an "unirom_withcaetla.bin", at that offset is 0x88 for me?

[Thelows]

I too found the "1BF90" offset. I guess I'm confused on terminology. I was expecting it to be "1BF97".

[JonathanDotCel]

Hi, yep, you're looking for something like this:

[Thelows]

This is what I see when I load it into HxD. in the 7th column I have an "88" instead of a "00" and the data looks different than yours.

[ABelliqueux]

FWIW, same for me

[JonathanDotCel]

My bad, may be a different Caetla version! For the last release I used the latest version of Caetla, it's cool and all, but it largely uses the memcard instead of writing directly to the eeprom, and doesn't come with a cheat list. This is being reverted for the latest version?

@Thelows Wanna jump on the psx.dev discord, and I'll send you something newer in the mean time?

[Thelows]

@JonathanDotCel heck yes! You guys are awesome. Do I need an invite link?

[JonathanDotCel]
