Thinking of getting the GF a DSLite (she got me the PSP), and considering getting a R4DS for it also? (good choice?) Just curious with the backup roms available on sites, its a dumb question but needs to be asked, the DSLite is multi-regional right? i mean a USA/JPY game will work on a UK DS right? Also does this look ok for a memory card for the R4DS? i.e. wont lag on performance, or does it have to be a certain speed?
