This loader simply execute the thread in kernel mode and execute the boot.bin. The problem is all UMD games have their own UMD device handlers in them and they access UMD drive directly, bypassing all UMD: disc0: device drivers. Therefore, a simply drive remapping will definitely not work. To have a real ISO loader, we need to patch some of the kernel system calls and/or the game itself. However, these will be very difficult to achieve as we will need to understand and reverse engineer the kernel calls.
how about this.. i havent try this yet but it seem to frezze right on the loading screen .. maybe the system is trying to load the save data from the MS . or at least trying to confirm some saves for the game. and when it doesnt find anything it freaks out.... and frezzes.. ?
ok i tried this with my own dump of hot shots golf open tee that i made using the umd dumper alpha v0.001. then i loaded the wab ms launcher alpha with kxploit. i then put the hot shots psp_game and umd_data.bin in the root dir of my 1gb ms. next ran the wab ms launcher. the screen just goes black. if i hit home nothing happens. to get out i would have to hard reboot or i found out i can just put my original umd disc of hot shots golf and the game will load then. after the game loads and i try to take the umd out it just freezes until i put the umd disc back in.
i hope this is helpful... i tried to be as detailed as possiable without rambbling on and on lol
Has anyone tried running a game off the MS (say wipeout) but have a different UMD in the drive (say mercury) this way you could see if it is actually accessing actual files on UMD or if it is checking for the UMD.
just a question. but are you sure that the UMD checks arent just checking for any UMD? for instance, has anybody tried loading a game from the MS with the PSP sampler disc in the UMD? prolly wont work, just wondering.
