1. MLT format in ZXVGS

Hello!
MLT screen format comes from MB-02 interface, which
displayed it on normal ZX Spectrum using Z80DMA chip.
But such files can be displayed on Timex computers
without extra hardware.
Only simple attribbutes remaping is needed, because
Timex uses attribbutes in the same lines order as the
first 6kB screen data (0,8,16,24,32,40,48,56,1,9...)
while MLT stores lines as they are displayed
(0,1,2,3,4,5,6,7,8,9...).
I've made MLT.RZX for ZXVGS that makes the neccessary
convertion and also moves BASIC program up, to 30720,
to avoid data clash. To activate conversion, MLT
pictures should be loaded with 14336 length (their
normal length is 12288):
LOAD *"IMAGE.MLT" CODE 16384,14336
