fr3nd / msx-vi Goto Github PK

MSX0 is the latest MSX machine that is being made popular through crowdfunding.
However, the included keyboard has a small number of keys, and there is no Ctrl key, so commands such as saving files and ending editing cannot be executed.
The msx-vi you developed is suitable for such MSX0.
We can edit with fewer keys.

However, there is one problem.
The MSX0 is so small that the text is too small to read on high-resolution screens. Can't you create a lower resolution screen version of msx-vi with larger characters?

Hi, what sdcc version do you use to compile msx-vi? When I try it on my macbook with v3.7.0 I get lots of errors/warnings.

When I fix the putchar and getchar with int instead of char I get even more errors/warnings:

First time I compile something with sdcc, only used msx-c before :)
