Nunuhara Cabbage 9a8ad87ae1 Merge branch 'master' of https://github.com/nunuhara/xsystem4 2021-05-01 13:59:12 -07:00
Nunuhara Cabbage 4f75f2d7ed Refactor sact_graphics.c 
Split the code from sact_graphics.c into sprite.c and hll/SACT2.c.
sprite.c contains an index-independent sprite/scene interface, whereas
hll/SACT2.c handles the indexing of sprites.

This is to better support the StoatSpriteEngine.MultiSprite_* functions,
which use a different indexing system.

Nunuhara Cabbage 851a19acc1 Work around for FFI heap reallocation bugs 
ref types are currently passed to HLL functions as pointers into the
heap. If the HLL function itself needs to allocate memory from the heap,
it can cause the heap to be reallocated, rendering these heap pointers
invalid.

In order to work around this, hll_call now guarantees 64 slots are
available on the heap before calling any HLL function. This is not a
great solution, but it should work to the extent that HLL functions only
allocate a fixed number of heap slots < 64.

This bug could be easily triggered by scrolling up on the message log in
Sengoku Rance.

Nunuhara Cabbage 899e928128 Fix bug in MsgLogViewer 2021-02-20 20:36:39 -08:00
Nunuhara Cabbage bd4c368966 Implement KiwiSoundEngine HLL library 
Used in SLC's (?) "media files" patch for the English translated version
of Daibanchou (enables .ogg playback).

This library is largely identical to the SACT2 audio interface.

Currently this doesn't loop .ogg music correctly. From what I remember
SDL_Mixer doesn't support setting custom loop points so this isn't easy
to fix.
