I tried both (rom uploader and ftp (filezila)) but it doesn't work. I'm gonna try tonight to put the games in an other folder just to see. How do we clean the cache files ? (i'm using pimame, not raspbian !)
You may have a fault in one of your memory blocks. SD cards get corrupted with use. Sometimes formatting can help. I recommend using the SDFormatter tool (rather than the windows/mac utilities)
As i said it, i removed 3Go (Mame4All) so yeah i think i have enough space. I tried to put the roms inside another folder but it doesn't change (i can only put files inside the roms folder). I'll try the cache clean and the formatter but if it doesn't work i'll have to install Raspbian =/
Linux can sometimes store deleted files in a folder called .trash-1000 or something like that. Its kind of like a recycling bin in Windows. Try deleting that too.
I ran some last tries : My SD card is 32Go. When i format using the SDFormatter she is now 29.7Go (FAT32). After installing using Win32DiskImager the PiMame is fully installated. I can upload one file (468Mo exactly), then start the next one (723Mo) and the download stops at 640Mo. I'm using FileZila, i tried everything, i think i will go on Raspbian and installing the PCSX emulator from here. I can't see where the problem is coming from, either i'm doing something wrong and i can't see it (i don't think the problem come from here), PiMame take something like 29Go or there is something blocking the upload of my files.
did you expand your file system? if not, in your console or ssh window, type 'sudo raspi-config'. Choose option 1, 'Expand Filesystem', Finish, Reboot.
