I'm a big roguelikes fan too. It's great that someone have managed to do at least an alpha of a roguelike port. (I've played rogue on Castaway, but it's not really adapted)
I've beginned to work on a Nethack port, but it's more complex than I've expected (multi plateform, code structure etc).
For now, I've only modified the structure (makefiles & co) to build a gp32 version. I have took and began to extend glibc wrapper from sdl port. But I'm thiking of doing a wrapper more like Darkfader's one (in mylib1). Because it looks much less work by the fact it use existing parts of glibc. I haven't fully understood how it works despite of looking at glibc code...
But I'm quite lazy, so it progress really slowly
I've read that GeneralNMX wanna work on a Nethack port too. Maybe we could join forces. (Bad luck, I'm traveling for work from tomorrow to the end of the week.) For information I'm coding using gcc on Linux. I don't know if what I'm doing will compile using dev kit on Windows or something else.
