I tried those out about 1.5 years ago and they run just about perfect EXCEPT there was no sound. I don't know if there is sound yet, but when I tried it there was not sound at all.
I'm still playing them both, once again no sound, and it's very slow. You'll need a high frameskip, but on an RPG, this is acceptable. Oddly enough, I've never played any other wonderswan games. If I remember correctly, quite a few of them are hacked/translated... sort of.
yes, my GP32 ist stable til about 256MHz
but i started a thread about the word "playable" some time ago. i don't get it, but i know that there are even people who actually watch camera-screened movies on their pc.
they will get eye-cancer one day...
