Hi there ,
i've just bought a subor D30 - as you may know earlier , this famiclone plays a bit lower speed than the real deal of nes , in past i had used mostly micro genius clones around but they haven't that problem , how can i fix that annoying speed problem in subor D30 please? changing the crystal on the motherboard is the solution? thanks in advance (:
This clone is probbaby PAL, so it is normal to be slower then NTSC
Yes you can replace the cristal, but you have to set "jumpers" too if the clone I s NOAC. If not you have to replace CPU and PPU also.
