NO$PSX - Error "loadlibraryfailure 0000007E"

Post by Xavi92 » June 13th, 2017, 3:45 pm

As the topic title describes, I am trying to load an original PSX CD-ROM (FIFA Football 2005 in this case) and try to run it under no$psx emulator, but I get the following error:

Am I probably missing some configuration parameters? I would like to use no$psx for debugging purposes, so using another emu is not an option right now.

The PC CD-ROM stuff is a little buggy I've noticed in NO$PSX. I've tried contacting NO$CASH about bugs in the emulator before, but he doesn't reply. Just rip your image and load it via a BIN object.
Development Console: SCPH-5502 with 8MB RAM, MM3 Modchip, PAL 60 Colour Modification (for NTSC), PSIO Switch Board, DB-9 breakout headers for both RGB and Serial output and an Xplorer with CAETLA 0.34.

PlayStation Development PC: Windows 98 SE, Pentium 3 at 400MHz, 128MB SDRAM, DTL-H2000, DTL-H2010, DTL-H201A, DTL-S2020 (with 4GB SCSI-2 HDD), 21" Sony G420, CD-R burner, 3.25" and 5.25" Floppy Diskette Drives, ZIP 100 Diskette Drive and an IBM Model M keyboard.

Reading directly from the PC's CDROM drive requires an "ASPI" driver. In other words: it works with win9x only.

Later windows version should provide some other way to access CDROM drives, but I don't know how, and (on my win98 computer without CDROM drive) it would be hard to implement/test that stuff.

Best/easiest workaround would be to copy the FIFA disc to a cdrom-image, and then use that image in the emulator. And using disc images works faster/smoother than real physical discs anyways, so I would recommend using disc-images even if the CDROM drive would work.

Nocash: Don't try and support direct CD reading on modern Windows. It will drive you mad! :p
It's a really bad case of mismatching API calls and proprietary (read: broken) hardware implementation.

If anything NO$CASH would write it all himself from scratch in assembler :lol:
