MC Exploit w/ HD Loader...FINALLY WORKING!!! –
After 3 days of non-stop trial and error and a bunch of CD-R coasters...finally got the damn thing to work.
My advice...use titleman.exe manually from the DOS command line to add your PS1 titles into the TITLE.DB file...DO NOT USE ANY of the GUI frontend apps. I tried using Title.db Maker v0.4.1 and also titlemanfrontend.rar...both just gave me black screen.
Start with a blank TITLE.DB.gz file (download attachment, if attachment doesn't show up in my post, search for it) and do "titleman.exe -a XXXX_YYY.ZZ" where XXXX_YYY.ZZ is your PS1's disc ID.
So in my NTSC PS2 MC's BADATA-SYSTEM directory, I only have the following files:
PS2 NTSC US V1 | PS2 Network Adapter | Maxtor MaXLine Plus II 250gb HD | Matrix Infinity v1.38
PS3 Slim | WD Scorpio Blue 750GB Internal | WD Essential USB 3.0 2TB
