E-UAE on AmigaOS4.1 (and MorphOS) supports only interpretive emulation and is quite slow compared to f.ex. winUAE.
What we really need is JIT 68K code emulation to speed things up. Especially AmigaOS4.1 users with slower machines would gain a lot from a JIT version of E-UAE.
The JIT will automatically become open source and other PPC OS, be able to benefit from it.
