ROM 920387 will not work with older cores. Older ROMs work with the latest core, so you may want to install the development core in slot 1, use 920377 or 920386 as your default MEGA65.ROM, then put 920387 in a non-default ROM slot such as MEGA652.ROM (where 2 is the ROM slot number: hold the "2" key during boot to select it). If you use ROM 920387 with an old core, typing will not work.
Known issues
FIXED in upcoming ROM release: Ctrl key misinterpretations: Ctrl P, U, V, W, Y, Z are doing the wrong thing. Ctrl S is both toggling pausing output and emitting a Ctrl-S PETSCII code; it should not be emitting a PETSCII code.
FIXED in latest development core: Key repeat appears to be triggering incorrectly, resulting in occasional unwanted repeated keys, possibly due to mishandling of the repeat delay.
The virtual keyboard registers are glitchy with the new keyboard scanner with regards to modifier keys. The
m65tool’s typing feature has been updated to accommodate this.
