2017-04-23SCI32: Add Lighthouse workaroundColin Snover
2017-04-23SCI32: Add kPlayVMD subop 27 (SetPlane)Colin Snover
Used by RAMA, when playing a video at the Hub Camp computer at the beginning of the game (room 1004).
2017-04-23SCI32: Add workarounds for RAMAColin Snover
2017-04-23SCI32: Add workarounds for LighthouseColin Snover
2017-04-23SCI32: Put Lighthouse restart game in restart save slotColin Snover
2017-04-23SCI32: Fix call to kFileIOIsValidDirectory in RAMAColin Snover
2017-04-23SCI32: Fix missing break statementColin Snover
2017-04-23SCI32: Reset ScreenItem cel type when updating from a VM objectColin Snover
In Phant2, when going to email on Curtis's office computer, a screen item that contained a bitmap on the last frame was updated to contain a view on the next frame. This crashed the engine when it tried to reuse the old disposed bitmap instead of the new view because the cel type was never changed from kCelTypeMem to kCelTypeView.
2017-04-22SCI: Add alloc_list command to debuggerColin Snover
This command lists all resources that are currently loaded into memory, plus the number of locks that exist on each loaded resource.
2017-04-22SCI: Avoid crashing when disassembling a call with a bad objectColin Snover
lookupSelector will raise an error if the passed object ID is invalid.
2017-04-22SCI32: Disable brightness boost when black-lined video is disabledColin Snover
The boost is intended to compensate for the darkness caused by the black lines, so should not be applied when there are no black lines. This fixes too-bright videos in at least LSL7.
2017-04-22SCI32: Store handle to VMD bitmap separately from ScreenItemColin Snover
In at least RAMA, when using the pocket computer to view a mail and then pressing the "return" button, the ScreenItem containing the VMD will be destroyed before the VMD player is told to close the video, resulting in a use-after-free trying to access the bitmap ID through the deleted ScreenItem.
2017-04-22SCI32: Fix bad interpolation of Robot audio samplesColin Snover
Previously, this code was interpolating samples if the previous block had missing samples, instead of interpolating when samples are missing in the upcoming block of samples.
2017-04-22SCI32: Add and divide instead of performing two divisionsColin Snover
This should make things trivially faster, and matches more accurately how the original engine worked.
2017-04-22SCI: Improve message when crashing due to a bad selectorColin Snover
2017-04-22SCI32: Fix dumb typo in CelInfo32::toStringColin Snover
The typo was `if (kCelTypeColor)` instead of `if (type == kCelTypeColor)`. Changed to use a switch instead for improved clarity and code intelligence.
2017-04-22SCI: Display class names in disassemblyColin Snover
2017-04-22SCI: Remove #undef for a macro that does not existColin Snover
2017-04-22SCI32: Implement support for QFG4 autosaveColin Snover
2017-04-22SCI32: Add workarounds & patches for QFG4Colin Snover
2017-04-22SCI: Explicitly label slot 0 as the autosave slot in the ScummVM UIColin Snover
2017-04-22SCI: Fix whitespace errorsColin Snover
2017-04-22SCI: Fix typo in debug messageColin Snover
2017-04-22SCI32: Fix broken final step of 2.1mid+ pixel dissolveColin Snover
2017-04-22SCI32: Fix bad kPointSize implementationColin Snover
Fixes text scaling gone mad in Phant2.
2017-04-22SCI32: Fix kStringFormat signaturesColin Snover
2017-04-22SCI: Accept 32-bit values to reg_t::incOffsetColin Snover
This fixes bad variable relocation in Phant2 causing the game to crash when reading object names.
2017-04-22SCI32: Enable support for SCI2-2.1 games in release!Colin Snover
Some games are not moved to ADGF_TESTING yet because they have not been played through completely: * QFG4 * PQ:SWAT Some games are not moved to ADGF_TESTING yet because they are broken: * Chest (fails to read/parse its custom archive files) * Hoyle5 (Poker DLL needs to be reverse-engineered; main menu needs to be "fixed" for budget derivatives that only contain some of the games and used Windows shortcuts to bypass the menu) * MGDX (missing MIDI playback)
2017-04-22SCI32: Provide more detail in console when a save game fails checksColin Snover
2017-04-22SCI32: Make version 41 the first supported save game versionColin Snover
Save games created by earlier versions of ScummVM are prone to having subtle graphics problems or other corruption caused by incomplete save/load code.
2017-04-22SCI32: Add palette code for late SCI2.1mid+ gamesColin Snover
Sometime during SCI2.1mid, the palette manager was changed to save and restore the source palette, and to add in-game gamma correction. Previously, only the vary start and target palettes were saved, and gamma correction was only configurable in SSCI by editing RESOURCE.CFG.
2017-04-22SCI: Fix compilation when SCI32 is disabledColin Snover
2017-04-22SCI: Do not sync objects when saving gamesColin Snover
Commit 5de2668939a6735da2b3438b7c586fc185791ef8 silently changed behaviour from running this code only when restoring a game, to running all the time, in an apparent copy-paste error.

2017-04-22SCI: Clean up unnecessary delayed restore flagsColin Snover
_delayedRestoreGame is always set and cleared at the same time as _delayedRestoreGameId, and _delayedRestoreFromLauncher is written but never read.
2017-04-22SCI: Move ScummVM save/restore to GuestAdditions and reimplement for SCI32Colin Snover
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.
2017-04-18SCI: Fix handling of buggy SCI0 export tablesColin Snover
The previous fix for this bug was incorrect; it only happened to work because of another bug: the number of exports was being read incorrectly (reading the byte size of the export block, not the number of exports), so the validation check for the export number always passed. Then, the "small" offsets that were seen were actually either invalid reads into the header of the next block in the script (KQ4), or reads into the bad first export table which contained an unfilled offset (Camelot). Once the incorrect number of exports was fixed, the previous "fix" broke in KQ4 because the export number validation started to work correctly and the first export table does not have enough entries (needs 2, has 1). This patch fixes the bug by using the last export table in SCI0 scripts instead of the first export table. (This does not affect most scripts, since only the buggy scripts have more than one export table.) Fixes Trac#9731.
2017-04-16SCI: Improve MidiParser_SCI robustness against bad sound resourcesColin Snover
1. KQ4 sound 104 has an extra 0xFC (MIDI Stop command/kEndOfTrack) at the end of the resource, which causes an out-of-bounds read because the filtering loop continues after the first 0xFC and unconditionally attempts to read 2 bytes (expecting there to always be a delta value + a command, whereas in this file there is only another kEndOfTrack command). This is corrected by exiting the filtering loop when a kEndOfTrack is encountered and there is not enough data remaining in the resource to continue reading. 2. KQ5 sound 699 is truncated, which causes the parser to attempt to read past the end of the resource. This is addressed by adding bounds checks that exit the mix loop early if there is no more data available to read. This allows truncated sounds to be played as far as possible (previously, trying to read truncated resources would result in a fatal error). 3. midiMixChannels allocates an arbitrary amount of raw memory for the mixed MIDI sequence, without performing any bounds checking when writing to this memory, potentially leading to a crash or silent corruption of adjacent memory. This is mitigated by using SciSpan instead of a raw pointer for the mixed data. Fixes Trac#9727.
2017-04-14SCI: Fix speech in QfG IV on big endian platformsThierry Crozat
2017-03-30SCI32: Check for game aborts in all kList iteration methodsColin Snover
This fixes a use-after-free in GK2 when restoring a second save game, when the List reg_t is still considered valid but the List has moved due to a partial game restore.
