Hi there,
I am not a dev , so I am sorry if I ask a dumb question : Can NDS emus be ported to DC ?
The NDS is a 67mhz console with 4mb ram, pretty low specs compared to the DC.
However, emulators are great on it mainly for 8bit era devices.
The DC miss some good full speed emulators (and ports) such as PCENGINE, GB colour (slow for some GBC titles), NEO GEO Pocket (I know that Ian is working on something).
Here are some emulators (with src) that run full speed on NDS via some hacks :
