Testing: DATA-GEAR (Z80-DMA) and HGFX

40% of the time by a CPU clocked at 14 MHz is still free, "waiting at HALT".

Lanex has prepared another game converted to HGFX.
This time he just removed attribute collisions and replaced some of sprite routines in the ZX screen.
He simply redirected most sprites to ZX-Planar layers, also to get different colours for sprites.

Apart from a hacking of a few routines, the game hasn't been edited, so it's still as slow and oddly synchronised as the original.
There is room for improvements and speeding up, because the HGFX routines are less demanding than the original zx-screen building.
Volunteers are needed... Or volume up the CPU speed in your eLeMeNt ZX.
The game is also playable in the LnxSpectrum emulator.
