2017-04-21SCI: Improve audio volume & settings sync codeColin Snover
This patch includes enhancements to the ScummVM integration with SCI engine, with particular focus on SCI32 support. 1. Fixes audio volumes syncing erroneously to ScummVM in games that modify the audio volume without user action (e.g. SCI1.1 talkies that reduce music volume during speech playback). Now, volumes will only be synchronised when the user interacts with the game's audio settings. This mechanism works by looking for a known volume control object in the stack, and only syncing when the control object is present. (Ports and planes were researched and found unreliable.) 2. Fixes audio syncing in SCI32 games that do not set game volumes through kDoSoundMasterVolume/kDoAudioVolume, like GK1, GK2, Phant1, and Torin. 3. Fixes speech/subtitles syncing in SCI32 games that do not use global 90, like LSL6hires. 4. Fixes in-game volume controls in SCI32 games reflecting outdated audio volumes when a change is made during the game from the ScummVM launcher. 5. Fixes SCI32 games that would restore volumes from save games or reset volumes on startup, which caused game volumes to be out-of-sync with ScummVM when started. 6. ScummVM integration code for audio sync has been abstracted into a new GuestAdditions class. This keeps the ScummVM- specific code all in one place, with only small hooks into the engine code. ScummVM integrated save/load code should probably also go here in the future. Fixes Trac#9700.

2017-01-09SCI32: Clean up SCI3-only opcodesColin Snover
SCI3 includes four new opcodes: * op_info[0x26][0] puts -info- flag in accumulator * op_infoSP[0x26][1] pushes -info- flag to stack * op_superP[0x27][0] puts -super- reference in accumulator * op_superPSP[0x27][1] pushes -super- reference to stack The implementation of these opcodes was correct already, but the opcode names given were a bit misleading (the value is not always stored to accumulator), and magic numbers were used for these opcodes in places. A review of the opcode table in Phant2 indicates that there are no other new opcodes for SCI3.

For whatever reason, this game uses a different global for specifying the text speed.
2016-11-20SCI: Improve disassembly outputColin Snover
1. pushi opcode now displays decimal value and selector value (if one exists) in-line 2. lofsa, lofss, and super opcodes now display resolved object/class names 3. Opcode arguments are visually aligned

2016-07-02SCI: Remove unexpected side effect from ExecStack constructorWillem Jan Palenstijn
The ExecStack constructor set argp[0] to argc before. This is now moved to the caller, to make this action more explicit.
2016-07-02SCI: Improve kernel subfunction loggingWillem Jan Palenstijn
ExecStack now stores the kernel call number as well as the subfunction. This allows kStub and backtraces to log the actual subfunction called. The kernel call number in ExecStack used to be stored in the debugSelector field. It now has its own field, to avoid confusion.

2012-06-23SCI: Change the program counter (PC) to be a 32-bit variableFilippos Karapetis
This is needed for future support of large SCI3 scripts. The program counter is isolated and does not interfere with other parts of the VM, plus it does not get stored in saved games, so it's pretty straightforward to convert
2012-06-18SCI: Add setter/getter methods to reg_t'sFilippos Karapetis
No functionality change has been made with this commit. This avoids setting and getting the reg_t members directly, and is the basis of any future work on large SCI3 scripts (larger than 64KB)
