FYI. You can use a SOP8 test clip to read/write the SPI flash chip without desoldering it but you need to press and hold the reset button during the reading/writing.

Thanks do much. "press and hold reset " is the solution for programming
You are the best

Here is my NES Maker software to create custom xxx-in-1 ROMs for VTxx based machines.

Download links:
V1.0.0 (initial version)
V1.1.0 (added support for SY-888B and SY-889 machines)
V1.2.1 (added support for Retro TV Games, Coolboy RS-18, FC Pocket and BittBoy machines)
V1.3.0 (added support for My Arcade Gamer V Portable Handheld machine, added various menu hacks, added game list save/load/clear buttons)
V1.4.0 (added support for Lexibook Cyber Arcade)
V1.4.1 (fixed non-working Lexibook Cyber Arcade .bin, added supported for more prg/chr size combinations)

If you select NintendulatorNRS.exe as the emulator then you can use the "Test" button to test the generated ROM.

Bonus (only for Mini/Micro Arcade Machine (240-in-1) [white])
Press and hold button A while powering on or resetting the machine to disable horizontal screen stretching.

we also need a version, where we can put our own menu music.

V1.5.0 (added support for My Arcade Retro Machine (200-in-1) [v2], which seems to use a different LCD)
V1.6.0 (added support for RED5 Retro Mini Arcade)

NintendulatorNRS does not (yet?) support the RED5 Retro Mini Arcade 240-in-1 menu due to missing data/code that gets loaded into RAM from somewhere. You can get it to work if you replace the 7 occurences of "20 1C 0E" (JSR $E1C) with "EA EA EA" (NOP NOP NOP) between offset $60000 and $80000.

I have several VTxx based machines and i would like to programm with my personal list

I have found how to dump and programm the memory, but I don´t have found almost nothing also this intereseting thread.

I don't have your programmer so I can't help you with that issue. I used a 3.3V modified $2 USB SPI flash programmer.

Could you tell me what that programmer is and what else I would need for the programm the memory?


Is there a tutorial how to reprogram these machines

Thanks

Could you tell me what that programmer is and what else I would need for the programm the memory?

I used this programmer (with a 5V -> 3.3V modification)

this test clip

and the "CH341A Programmer v1.4" software to dump/program the SPI flash chip.
