Re: Algunas versiones del core PC de pruebas/experimentos propios...

Almost anything. It is unstable. Sometimes I get to some game, sometime it freezes on a DOS prompt, often in Volkov Commander. I suspect an SD card communication a little, I will try another one later.

Yes, IS61WV20488BLL-10TLI. ZX Uno v4.1. It works ok with normal PC/XT core on 70 MHz RAM, but this one freezes.

The 18-bit DAC is OK, the output seems to be correct, but the 18-bit DAC XT core is very unstable on my ZX Uno. It freezes a lot.

The 18-bit DAC core works, but is very unstable on my ZX Uno. The HDMI core does not have HDMI output. Maybe I have wrong HDMI interface, are there any test for it? Which version did you use?

Re: Core PC/XT BETA

And what about to use internal SRAM as video RAM and maybe ROM and external SRAM as computer RAM?Is it too complicated?

Re: Como preparar una imagen de DOS para el core PX/XT?

I did it quite easily. I attached the SD card as physical drive to VMWare, formated the partition and installed the MS-DOS 6.22 from virtual floppy images. You can download it here http://www.8bity.cz/files/PC/SD_ZXUno_P ... _Image.rar

Re: Core PC/XT TEST1 unificado (20170218)

Thanks. Both internal cores work for me, but it is similar as before. The GP Cycles http://www.8bity.cz/files/PC/CYCLES.zip works on 512k and not on 2MB core. And it seems to work OK in EGA mode (just the hacktro screen is scrambled), but the game is OK, the CGA has some scramble attributes on the s...

Re: Core PC/XT BETA para ZX-UNOs con 2MB

I found strange thing. When trying The Cycles (Grand Prix), the 2MB core (does not matter if 50 or 75 MHz) gives me message "Packed files is corrupt", while the same game works with 512kB core quite well. If you want to test, I put it on http://www.8bity.cz/files/PC/CYCLES.zip for download.
