PSP 개발자인 PSMonkey씨가 제작하고 있는 닌텐도64용 에뮬레이터인 Donkey64 베타버전의 실행 동영상입니다.

현재 에뮬레이터의 속도는 마리오카트64에서 30~40프레임 정도가 나오고, 마리오테니스64나 NBA잼에서 20~30프레임 정도가 나옵니다.

닌텐도64 에뮬레이터가 PSP에서 메모리를 많이 차지하기 때문에 반드시 커널모드로만 접속을 해야하고, 이것때문에 에뮬레이터는 펌웨어 1.0 또는 1.5에서만 작동이 됩니다.

현재 개발중인 차기 버전에서 다음과 같은 기능을 추가할 예정입니다.

- 60프레임까지 지원
- 44k 주파수의 사운드 지원
- 무선랜 기능을 이용한 멀티플레이 기능 지원


개발자 코멘트

Full N64 emulation using every aspect and power of the psp. Because of that, right now Donkey64 only works on psp versions 1.0 or 1.5 because of its kernal usage. I do intend however to develope a version for psps 2.0+ using the new eboot loaders later on once Donkey64 is stable on version 1.5

Right now sound is very glitchy and not in sync with the video protocalls. I believe this is because the psp can't keep up with both the video and sound processing. I believe I may need to rewrite some operational codes for this.

Also, Donkey64 seems to run slower and slower once more and more time passes playing the emulator. After playing MarioKart for 10 minutes, the game becomes soo slow that the emulator just crashes after awhile. I may need to do some more work on the dynamic recomplier to compensate for this.

I have been getting around 30-40 fps on MarioKart64 and around 20-30 fps on other N64 games such as Mario tennis and NBA jam.

Features so far in Donkey 64 include: Full original memory pak emulation form the original N64 counsel. Also I have a built in full save/load state of a game. However, it takes ridiculous times to both load and save a state and each save state takes almost 2 megs of space on the memory stick. Full screen is also implemented as you can see in the video. Sound is at the lowest frequency at 11025k. Even at that low frequency, sound is very glitchy and shoud just be turned off. Screen shots capability has also been implemented. Button configuration has been set so that the user can choose his or her own combination of buttons to use for each particular game. There are several default configurations if the user decides to just use the default configurations.

Things I intend to do in later bulids:
Faster engine proccessing - to run every game at 60fps
Superior sound performance - to play sounds at 44k frequency
Implement cheat codes for each game
Try to include multiplayer support for using 2 people on one psp and also using 2 psp connected wireless
Redo some of the dynamic recomplier codes
Release both the beta eboot version and the source code to the general public in a couple of weeks so that other people can add to the code and make Donkey64 even better.
