This project is a proof-of-concept RISC-V emulator aiming at near-native execution performance on LoongArch. Support may expand to other architectures in the future, if the techniques employed here prove useful and reasonably arch-independent.
The project is named after a popular but extremely difficult chart with the same name, in the rhythm game maimai. Binary translation is hard, running such logic in privileged mode is even harder; while I cannot play the maimai chart at all, I do hope to manage the difficulty here somehow!
- RV64GC disassembly
- verification interpreter -- WIP
- emulation machinery
- guest MMU -- barebones
- linux-user emulation
- stack -- works okay
- thread-local storage
- syscalls -- WIP, only
