First of all i'm not Dude if more Sir or Mr. I don't know you and certainly i'm not your friend...
Moving on... downloaded the games mentioned above and using my freedos 1.3-RC4 i was able to run Test Drive 2 and Grand Prix and Cycles ran the intro fast and exited with a error code. Test Drive 2 played and exited with a error. I grabbed my floppies with the same games (except for cycles) they did not run, got a black screen and no error output. Runnnig on a VM Freedos 1.3-RC4 and 1.3 Live And the final question what do you want with Freedos if you have and quote " I also can use from CP/M-86 to all MS-DOS oficial releases to Windows 98 stripped FAT32 MS-DOS. PC-DOS, DR-DOS, whatever. " They should run games better than Freedos! On Mon, Mar 7, 2022 at 8:43 PM Carlos Teixeira <carlos.t...@gmail.com> wrote: > Dude...
