GSoC is nearing its end, \u00a0today is the “suggested pencils down” date, means there shouldnt be much more happening that some cleanups and bugfixes. Im already doing exactly this for a couple of days so I guess its time to round up what got done (and what didn’t)<\/p>\n
The modplayer is fully implemented and accurate in regards to the player in the MI-Executeable. Actually it has some more effects and parameters implemented and can play alot of TFMX\/Pro Modules, albeit with some issues (TFMX was often modified for games so this is no surprise).<\/p>\n
Integration in scumm engine<\/strong> The modplayer is complete, it implements everything the original player (sources from UADE) did, even some optional effects (microtonal and modulation, both can be enabled with compiler macros). I cant vouch for the accuracy, I only tested the songs from Kyrandia so far and they only need a subset of the player. Especially the optional effects would need testing. There are some audible differences as effects are played in the intro as channels from the music are replaced – this is not 100% like the original player.<\/p>\n Integration in kyra engine<\/strong>
\nuses 2 seperate Player instances as this allows music and effects to peacefully coexists without the latter stealing channels from the former, and this also means the mixer-settings (Sfx, Music Volume) are automatically supported.
\nDownsides are the additional memory required for the second player-instance (music-data is shared) and higher CPU-load if more than 4 channels are active. Neither is a serious drawback as the additional Memory is less that 700Bytes, and the CPU-load should be manageable. When I tested MI Amiga on a PSP, running music had an impact of additional ~10% load and that was with a downclocked CPU (111Mhz instead of 222) and highest Samplerate possible(48KHz).<\/p>\nMaxTrax<\/h3>\n
\nSince there are rarely more than 2 channels used for music, Im only using 1 instance for music and effects. The game is a bit of a problem as support for the Amiga-Version is currently incomplete in ScummVM, lots of tables are hardcoded in the executeable and even different sections of the game behave (slightly) differently when starting music\/effects. I have implemented support for all sections, but I am unable to thoroughly test it. For sfx 2 tables are needed which are directly in code ATM, but should find their way into kyra.dat later.<\/p>\nDesktoptracker<\/h3>\n
