Note: For those interested, the Russian “Phoenix” project is also attempting HLE emulation and results so far are impressive! I believe it is in closed beta, and be aware that there are fake versions of this emulator out in the wild. After staring at disassembly for countless hours, I cancelled the attempt in early 2010. However, the HLE approach was proving to be too laborious without additional help. Progress was reasonable, and I managed to get the CPU emulation concrete enough to run many of the non-Opera binary files like the mildly famous sonic example (the screenshots of this are still available on the sourceforce site, for any emulation historians interested). The aim of the project was still the same as it is today: to provide a full-featured, open-source emulator for 3DO.Īt the time I was attempting a high-level emulation (HLE) approach. I had been eager to see an open-source 3DO emulator and was disappointed that there was still none available. It’s probably not commonly known that 4DO was first started about 4 and a half years ago in 2007. Game compatibility fixes (mainly through the efforts of Viktor!).Intuitive controller setup, native joystick support, and support for up to 6 players.The development of 4DO has introduced several unique features as well: It’s been a overall a quick revival since the release of the FreeDO source code, and 4DO now provides 3DO fans with a clean, functional emulator.ĤDO was able to inherit many great features from FreeDO: high-definition rendering, clock speed adjustments, and the impressive emulation accuracy! The FreeDO user interface was not open-sourced, but the resulting rewrite for 4DO was an overall benefit.

The emulation is in a good state, and the primary features of the emulator have been stable for quite a while.
