Right, third version uploaded, same place as before: http://www.phlamethrower.co.uk/misc2/arcem-src.zip (Source) http://www.phlamethrower.co.uk/misc2/arcem.zip (RISC OS build)
Compared to the previous version, this one features: * New display driver for palettised output (arch/paldisplaydev.c). - It's somewhat similar to the stddisplaydev code, in that it needs to be #included directly with a bunch of #defines/etc. set up in order to allow it to interface with the host OS in the cleanest/most efficient manner. - The driver is able to convert the source data to any bit depth equal or higher than the source depth. (Well, not quite any depth - only depths which are powers-of-two are supported). - The driver also supports horizontal & vertical upscaling, like the stddisplaydev code (Although like stddisplaydev, there are some restrictions - horizontal upscaling must be a power of 2, and each source pixel must convert to no more than 32 bits of output data). - BPP conversion & upscaling is actually done through a lookup table, which made the code nice and easy to write, but won't always be the best for performance (e.g. for 4bpp or 8bpp source data, which is probably the ones people will encounter the most. Oops!). But if BPP conversion and upscaling aren't in use then it will just copy the data straight to the output, so it's not all bad. - Since it won't support mid-frame palette swaps, it just refreshes the screen once per frame instead of one scanline at a time. - This driver supports frameskip, which may be a useful performance boost on some hosts. (stddisplaydev currently doesn't support frameskip, but it shouldn't be too tricky to add it) * Amiga & GP2X display code has been modified to use the palettised driver. So with any luck both those platforms will work with only minimal fixes. However I haven't tried to add any endian swapping code, so you might need to sort that out yourself, Chris. The routines which do the data copying are in arch/displaydev.c, so that's probably the first place to start. I have a feeling it might be easiest to write seperate versions for big-endian hosts. * RISC OS tweaks: - Added a tweak menu available by simultaneously pressing both Windows keys on the keyboard. This allows some of the display settings to be tweaked at runtime. - If enabled in the tweak menu, screenshots can be taken by hitting Print Screen - The tweak menu can also be used to toggle the display of some simple performance/display stats. - Supports both the palettised & standard display drivers. Driver can be selected at initialisation via a new command line option, or switched at runtime via the tweak menu. Let me know what you think.
