1. Platform support under construction. Unavailable for the end users.
2. No hardware support.
2. Not available on Ricoh processors due to the lack of hardware support.
3. All 6502, 65SC02 and 65CE02 instructions are supported. 65C02 bit setting/testing instructions, some HuC6280 instructions and some 65816 instructions and addressing modes are not supported.

5. Zilog syntax only.
6. Optimized for the processor in the emulation mode used as an accelerator for a 6502-based system. Doesn't utilize its full capabilities in the native mode.

* 65816 code is quite suboptimal. If you're targeting a 65816 machine only, consider using something else for the time being.
* Intel 8080 and Gameboy support added right now would mean no support for stack variables.
* CPU's from the 6800 and 8086 families might be added in the future.
