Can anybody shed any light on what is happening here? The same files load fine through ps2link off PC host:

The following is the extended debug output. Sorry there is a lot of it.

emulation started

It seems to fail to recognise the rom files, although they do appear to open and part of them is read. I don't think this is file corruption on the hdd, I copied the files back to PC host:, loaded them with ps2link and the emulator runs properly. The IRX modules load with fakehost without any problem, as does the program elf, so I am at a loss as to why the rom files are not. I should point out that the roms are of sizes 4k and 8k, but I'm assuming that the emulator just reads the first 1k to determine their validity.

Any ideas or suggestions?
Regards, Tommy.

Checking ps2drv/common/include/errno.h, code -2 means the file wasn't found. Within the pfs0:/PS2TESTS/ps2vic/ directory, are you sure the rom files are named exactly the way open() expects them? If they are then you probably want to check fakehost to make sure it doesn't do anything funky to the passed-in filename. Look at the "real" filename passed to the pfs driver, the one returned from fd_name() to the open() call (in fd_open()). If everything looks good there, then your next place to look is in ps2fs itself. I just looked in pfs_fio.c and noticed pfsOpen() returns ENOENT right off the bat if the passed in filename is NULL. openFile() (called later by pfsOpen()) is another place where ENOENT is returned.

Use the source, that's what it's there for.

This issue has been resolved now. Hopefully we can expect to see the updated version of PS2VIC available soon, if it isn't already. Raipsu was good enough to equip me with a fixed version, and it loads very effectively through fakehost now. Very nice it is too :P
The problem was due to the method of file access used in PS2VIC, I understand the same effect was apparent when the ps2vic.elf and rom files were installed on memory card. Changing to fioOpen/fioRead etc. has fixed this. Thank you for your swiftness in doing this Raipsu.
You are right about the -2 error MrBrown, roms.rb was not included; although this file is not essential to load the emulator. Repeated attempts were made to open roms.rb though, when the files basic.rom, kernal.rom and chargen.rom had failed; this was probably a distraction from the real problem, and I should've perhaps deleted this extraneous debug output, but I felt it was relevant.
