PsyQ CD Emulator with SCSI2SD?

[Jackhead]

Hi there,
i want to get a SCSI2SD board for my Playstation CD Emulator. It will be handy to use a SD Card instead of a old scsi drive. Did anyone try to use a SCSI2SD on the board? Im not sure if i choose a V5.5 or a V6. Depending on the Speed.
Goal is creating a partition with the scsi2sd and upload games into it to run with cdboot.
regards
Chris

Ok i will test it. I ordered a SCSI2SD V5.2 hopefully the psyq Software will work with it.
Goal is to boot Games from SD on a real PS Devkit setup. Will be fun, i also want to learn more about the cd format.
I will post here some updates. For the moment i connected a internal scsi cable and put it outside the case. Hopefully get the scsi2sd this week to start testing.

Yes, I've used one on my CD Emulator and it does work. Sometimes it does glitch out when using CDDISK.EXE (usually after having loaded a game/image from the SCSI2SD), so I just installed a real SCSI HDD and I haven't had any problems since.

The SCSI2SD I was using though was old. It was the model from 2016 or 2017 I think.

@Shadow i need your help with the Emu.
I have problems launching software from the emu hdd.
First at all i configure the jumper on the Emu to 390/i5/D7 SCSI ID:7 No conflicts with other boards.
On my Bios i reserve it IRQ5 to ISA.
CDBios is starting correctly. After that i to the menu cddisk, first setup with -n 0 (my hdd is id 0) and create a parti.
What Bootloader do you use?
After that i use buildcd to write the rcube sample to parti 1. Also fine without errors..

But now when i start my h25bios (h2500) and change to the Emu with "run selemu" it tells me that target is connected but it cant open the input file??? After i choose the emu (selemu) when i did resetps 1 i hear that the kit is on emu mode because the cd drive do not react any more.
First i was thinking its because the scsi2SD. So i found my old 4GB SCSI HDD (its the IBM that is in the manual) but same results. Any idea what i miss or do wrong?

When you write the RCUBE sample via BUILDCD, make sure in the CTI sheet the SYSTEM.CNF file is the first one in the hierarchy. Also make sure the CNF text is correct and it points to the correct PS-EXE (IE: the "BOOT" string value).

I got it. The system file is not really needed for the sample. So far i found the problem.. It was i run the commands in a dos prompt window in win98. Looks like the cdemu dont like that.
Ok its working:




Did you use cdgen for creating .cti files ?

No, you use GENCTI.EXE. It will read every file and directory in your working directory and create the CTI (so it needs to be edited after usually to remove a few non-needed files). The SYSTEM.CNF sheet must always be the first file on the disc as well.

Code: Select all

REM Make the CTI sheet (edit it as needed afterwards)
GENCTI game.cti

REM [SCSI ID 0] on [Partition 1]
BUILDCD -mcd.map game.cti -s0:1 -zus
