Hello: Remember to rename curscr variable in source file sdlmain.cpp with another name (for example curscreen), because it is in conflict with curscr used in several modules of libpdcurses package included in DOSBox source code. thanks

In future releases of DOSBox, could you put SDL2 binaries (SDL1 binaries don´t work in Windows XP) compiled with mingw with debugger enabled? I have to compile myself (using msys32 in Windows XP) because there is no SDL2 version with debugger enabled that works in Windows XP.

The source file sdlmain.cpp of DOSBox should have the variable curscr declared with other name than curscr, because it is in conflict with curscr used in several modules of libpdcurses package included in DOSBox source code

I have done one test: have a speedstar VGA with BIOS 4.23 and RAMDAC SC11486CV (32768 colors), removed the SC11486CV RAMDAC and put a SS2410 RAMDAC (16 million colors), then the 32768 colors does not work, this means BIOS versions 5.01 and 6.01 have code to deal with more modern RAMDACs like SS2410 …

I have used a CRT instead a TFT monitor and the card works, the image is garbled. Could you verify if your card works without loading sr340.sys in the config.sys? If I don´t load sr340.sys in the config.sys file tigademo.exe does not work. Could you send me your tiga.cfg file? In this cfg file are …

I use msys32 with gcc version 5.3.0, I have compiled with -march=i686 -mfpmath=387 and the built dosbox-x.exe does not work on Pentium III computer but works on Pentium 4. It seems that from versions 0.83.5 onwards dosbox-x need at least Pentium-4 CPUs to run.

Do you know if it will be any patch to run dosbox-x in Pentium-III machines? Latest github source code compiles without problems in Pentium-III, the problem is that the executable (and the official mingw release) do not work in Windows XP with Pentium-III CPUs. One user pointed the AVX emulation was …

Have you used the card with a TFT monitor (60Hz refresh)? Maybe because I have used a TFT monitor instead a CRT (tube) monitor I do not see any image in the screen when I run tigademo.exe, the output signal of the tiga card could be 1280x1024 but 75Hz vertical refresh instead 60Hz (the native …

Could you do the following test? Remove all sims and let me know if it works, it seems to me that the board needs at least one DRAM SIMM module, because if you remove all SIMMs modeules the only memory the board has is the VRAM memory located under the two BIOS chips.

Try to add Windows 3.1 sound support, the reason I found diagnose.exe didn´t worked was that because Windows 3.1 sound didn´t worked tried to run low level programs to check for sound and diagnose.exe was a good one.
