Please look up, I have put the document in the attached files here Re: SDLPAL DOS port for the RPG game LEGEND OF SWORD AND FAIRY. I test it with new SBEMU and VDPMI loaded, it is working. Just one issue, on an i845GL PC, the FreeDOS startup stops when loading VDPMI.

Thanks! I tested the sdlpal in virtualbox, it seems that there is a keyboard input problem that the game doesn't read keyboard port suddenly, key press has no effect in ingame-menu, and causes VDPMI keyboard buffer overflow and there is a intentional NULL pointer write to trigger a exception 0e. I've made changes when kbd buffer is full, the buffer is cleared/discarded so that there is no exception, but the underlying reason why sdlpal doesn't read keyboard is unknown, it still could be related to VDPMI, I'm looking into this.

FreeDOS is not tested yet, I will try to figure out what happens during loading.

About the better video support, is there an new implementation available now? I know the current one works, just not so good when running under DOS.

I've no idea the currently state of video support of SDL, but I can SDLPAL works well on that. if it has better solutions, it can be useful.

Using the same boot disk, only that i845GL PC has the problem, while the PM965 PC boots normally.

I remember this keyboard problem, but it's not universal. What is the testing results of real hardware and DOSBOX/86BOX, etc.?

Also, is surround OPL working for you? In the SDLPal.cfg I packed, UseSurroundOPL is enabled. If you can hear the stereo Ad Lib music, it is working.

Oh, I need to clarify that SDLPal does not use SDL level video decoder component, nor does it use SDL_Mixer.
