This is my first beta version of the TMS9928 VDP Mode 2 implementation.
Sprites are not finished yet, so not included.
System main clock is 21,42857 Mhz (50 * 3 / 7) but VGA is running at 25Mhz.
A line-based buffering allows the clock synchronization.
SDcard loader are faster now using MasterClock / 2,
but it's track based and no FAT is supported yet.
The video shows the system startup 2 times in order to underline the new SD loader speed.
Enjoy...
