Hi all, I have a CPS3 board (model 95682A-2 - see attached pic) that I'm looking to replace the optical drive with the ZuluSCSI RP2040 Compact (https://store.rabbitholecomputing.com/ZuluSCSI-Compact-RP2040-p/zuluscsi-compact-rp2040.htm). I have regular SIMMs that currently have SF3 2nd Impact installed on them, and am hoping to install other games once I get an additional 128Mbit SIMM, but am hitting issues that I think might either be an ZuluSCSI issue or an CPS3 repro cart issue.
I have a Darksoft repro CPS3 cart with UltraBIOS + NoCD, and a Standard SH2 - see the attached pics.
When booting the board with the original SF3 2nd Impact cart and CD inserted in the physical drive, everything works as expected and can play the game/re-flash the game to the SIMMs with no errors.
Once I swap the original cart out with the repro cart, hook up the ZuluSCSI and hold P1 shot 1 to get into the cart menu to flash the SIMMs, once I've selected the region, the interface locks up. I know this typically means the wrong UniCD image is in use, but I've verified that I'm using the right image (standard SH2 ISO). I've used a bunch of different ISOs and they all lock up after selecting the region - see below for the images that I've copied to the ZuleSCSI and tried with no success:
UniCD-CPS3_for_standard_SH2_V4.iso
UniCD-CPS3_for_standard_SH2_V4_Unmodified.iso
UniCD-CPS3_for_standard_SH2_V4th Strike.iso
Mitsurugi_w_NoCD Utility.iso
UniCD-CPS3_for_custom_SH2_V5.iso
I've also tried different SD cards and different filesystems (FAT32 and exFAT) on the cards, updated to the latest ZuluSCSI firmware and renamed the ISO images to CD1.iso to ensure no file character limits are being hit. I've attached the ZuluSCSI log file for reference and it looks like the ZuluSCSI is working as expected as I can browse the ISO contents via the cart menu option 2.
Next step is to burn a physical CD of the UniCD to make sure the ZuluSCSI isn't getting in the way for some reason.
Really at the end of trying things and what it could possibly be, so any help or guidance would be greatly appreciated!
