[EZFLASH4] Trained ROMs don't work or what am i doing wrong?

Hi all
after some years of not playing i bought myself a GBA micro (to complete my hardware) and an EZ-Flash IV.

but there is something different on the micro, trained games do not work:
1. gfx errors in the trainer
2. crashes before real game

i tested this with my gba sp and there the games work...

is there a solution to this problem?
