Here is yet another entry...

This program can be used to change CPU mode on MSX tR.

3608 DEFUSR=-32749:IFUSR(0)THENLINE>2COPY0&H80F6OR384BASE!!

Change number after "LINE>" like this:
0 = Z80 (ROM)
1 = R800 (ROM)
2 = R800 (DRAM)

This program has also another special feature... If you save this program with .COM extention, you can use it on MSX-DOS as well.

Example:

SAVE"R800.COM"
_SYSTEM
R800

Hehe, I was just thinking you wouldn't get any bonus points but then you came up with an even more insane version

I think he reads the pointer to the basic program (#f676 + 256*#f677), then add a offset of 38 bytes(used by the real basic program) and then executes a clever Z80 code defined with BASIC tokens and data.

Yes it isn't really an MSX basic program. It is just a reverse basic of a small program that sets the CPU mode. Asembler code is usually not allowed in basic contests so I doubt that this entry would count although the idea is brilliant and the entry looks very good
