Ok this may be a long and complicated story but here it goes. I have 3 playstation emulators working perfectly in GameEx pSX 1.13, ePSXe 1.7 and pcsx-reloaded. I use 2 sets of isos for playstation. The first set are old mixed images like mdf mds img bin cue for pSX and ePSXe 1.7 and the second is the playstation redump images for pcsx-r. For pcsx-reloaded, it gets a bit more complicated since I use redump images which are multibin and cue files. I mount them with launch before and launch after with Daemon Tools lite 4.35.6. The advantage to this is I know the images are dumped correctly and I don't have sound issues but I sacrifice emulator accuracy (pcsx-r) for the ability to launch these particular images. Now for the point of this thread. With the ARBEX emulator I tested loading the mixed image (sketchy) formats from the commandline config posted by Headkaze which was ARBEX.EXE -IMAGE "[ROMPATH]\[ROMFILE]" -RUN2 -FULL They load fine as long as the image is a single bin or mdf or img file. So far so good right? GameEx can launch ARBEX images without Daemon Tools and all works well. The next step I wanted to take was to see if I could mount my redump images in Daemon Tools and have ARBEX load them via the -SPTI commandline which launches CDROMS not images. This is where it gets tricky. OK, so manually outside of GameEx for testing purposes, I load up a multibin redump image using the .cue into Daemon Tools. I go to ARBEX and load CD ROM via SPTI. After pointing it to the mounted game the only way it will "Start" is by finding a file whose name and extension change depending on the game but always starts with SLUS_xxxxxx. After I manually find this file, ARBEX loads up the redump image perfectly and all is well. Well why am I doing this and whats the point you may ask? The redump images are the best set I've found and ARBEX is one of the most accurate playstation emulators that can actually load these images correctly. My ultimate question would be is there a way for GameEx to select this SLUS_xxxx file which will have a different name and extension for each game once mounted and load it after it "finds" it? This pic shows a mounted game in Daemon Tools and the magic SLUS_file that needs to be loaded with the -SPTI commandline. Basically Headkazes config works if you switch out -IMAGE for -SPTI and have it "look" for a SLUS_ file then add the -RUN2 -FULL switches after. The order should go like this. 1. Mount game in Daemon Tools. 2. Use -SPTI commandline to get the "Open" dialogue. 3. Find the SLUS_ file and select it. 4. -RUN2 - FULL and any other residual switches. 5. Success!
