Blassic is a classic Basic interpreter. The line numbers are mandatory, and it has PEEK & POKE. The main goal is to execute programs written in old interpreters, even those that use peculiar control flow constructs or automodifiable code. However, it can be used as a scripting language, and has some not-so-classic instructions. It has graphics modes that are compatible with some classic systems and user defined.
Aliados is a CP/M 80 emulator. Instead of emulating a machine and running some variant of CP/M on it, it emulates only the microprocessor and captures all CP/M system calls to execute natively. It does not need to create disk images, but reads and writes on the native filesystem all files that match the CP/M naming conventions.
