What ROMs do you have that have so far unresolved issues with R4DS? I've heard that Pokemon Platinum has problems(I haven't tested yet but will be soon) and I had problems at first with Final Fantasy Crystal Chronicles: Echoes of Time however after patching with DSATM it loads fine with R4DS Firmware 1.18(however now it doesn't load correctly in YSMENU...go figure).
EDIT: 3541 Pokemon Platinum(U) works with R4DS Firmware 1.18 after patching FW with Yasu's R4Custom(although the Firmware's now in another language...)
