Did you have problem on real console?
Hi,
Do you already have some "surprise" when you try your game on a real console instead of an emulator?
I tried my game (under developpment) on a real console (thanks to the 128 in 1 Flash multicart cartrige of AtariMax).

I solved my problem!!
So as PKk (billions thanks to him) pointed to me , it was well the problem of sprite cloning.
The problem occurs with sprites above number 8.
The problem is linked with mode 2 initializations.
Reading MSX forums ,the sprite cloning occurs when bit 0 and 1 of VDR reg 4 are set both to 0.
My code was the following :
screen_mode_2_text();
disable_nmi();
rle2vram(PATTERNRLE,0x0000);
where the PATTERNRLE has been generated by daniel's tool : ICVGM30
