I just installed the Wood RPG firmware. So, I am going about cleaning up my R4 system files. I don't know what I can and cannot delete. I was wondering if anyone could help me out. My file hierarchy looks like this: /.Trash-1000 /_rpg /_system_ /DATA /font /fonts _DS_MENU.DAT _DS_MENU.NDS _DS_MENU.SYS _DS_MSHL.NDS aplha6.diff cloud.pal copying fmod.dll iq-points link.pal xpa-mdsw.r00 I have actually been wanting to delete some of these for awhile but didn't want to risk doing anything damaging. I tried Googling a few of them but couldn't find any info on them. I assume that the _DS prefixed files can be deleted due to them being R4 firmware files but I want to be absolutely certain. If anyone can help me out I'd appreciate it.
