Now yes, the images are seen.
As you can see, Juan Luis, the same corruption comes out.
I have implemented, in your code, the previous deletion of the pattern zone, but corruption in real HW persists.

Does the corruption appear just after command execution?

Manel46, try to comment all flip_ calls (lines 62, 63, 64 on sprite-test2.asm), although nothing flipped appears on screen. It's to discard the possibility of corruption due to BMXL commands.

After this, if corruption is still present, try to comment line "call upload_sprite_linear". Perhaps I should upload the sprite graphics (in linear mode) in other VRAM address.

Hi Manuel. I have uploaded the source code in Google Drive. The execution in OpenMSX and real hardware are different. We don't know why. We are analyzing the problem.

Alexito tells me that he can't open the .rar file with source code. Manel you were able to get it. Weren't you?

I'm using WinRAR 5.70 (64 bits).

Is there more people with this problem?

I have downloaded via wetransfer right now and still I can't open the .RAR sources my winrar version used was 3.61 if you can use .ZIP I think is more compatible for everyone.

Yes, I could open the winrar. I use "Bandizip 6.24", which opens everything.

I have downloaded via wetransfer the file in .ZIP format now I can see the assembly program. Thanks, Juan Luis for share your test program because I have not touched my V9990 for a while but I like your discoveries and I want to learn more about BMXL

Horizontal and vertical mirror works well with BMXL comado. This is done in R # 44. setting bit 2 to 1, for horizontal symmetry, and if you put bit 3 to 1, you have vertical symmetry.
I made a little rom with this. It is in B3 BD16 mode, because I had it on hand. It works the same in Openmsx as in real HW.
Juan Luis, I will send the code.
