2017-05-20SCI: Find and store the original static names of objectsColin Snover
See code comment in Object::init for more details. Fixes Trac#9780.
2017-05-13SCI32: Fix crash at end of TorinColin Snover
This "fix" is more of a hack, in the interest of making the game completable. The root cause is a combination of two problems in the game scripts: 1. Blink::init expects to receive either 0 or 2 arguments, but it assumes that if it received *any* arguments, it must have received 2 arguments. This assumption is wrong, though, because-- 2. soTorinWhoAreYou::changeState(0) calls poPecandEyes::setCycle(Blink) without including a second argument (the blink speed). This ends up with the second parameter being some garbage, and that garbage gets sent to kRandom which then complains about receiving garbage. The correct fix for this would be to fix soTorinWhoAreYou (in script 51400) to pass a second argument to setCycle, but there are not enough obvious spare bytes for a quick and easy patch, so this workaround will have to do for now. Fixes Trac#9779.

2017-03-30SCI: Stop getCurrentCallOrigin from mutating stack framesColin Snover
This fixes incorrect backtraces after a workaround failure or other call to getCurrentCallOrigin when one or more stack frames are calls to local procedures.

2017-02-26SCI: Clean up kRandom + allow 0 parameters via signaturesMartin Kiewitz
Also added in depth comments about the currently known variations Returning the RNG seed is now implemented (although it seems no games actually use this functionality, it seems to be just script bugs). Also remove Torin kRandom workarounds.

2017-01-01SCI: Fix PQ2 crash reading second page of files in jailColin Snover
This fixes the crash in PQ2 1.002.011. There is another workaround for the same problem from ticket Trac#5223, but it uses a different method name that does not match in this version of PQ2. Fixes Trac#9670.
2016-12-19SCI32: Generalize Phant1 kArraySetElements workaroundColin Snover
This bug exists in a system script that is called from many, many rooms, so it is simpler to just make the workaround apply to all rooms.
2016-12-18SCI32: Simplify workaround commentColin Snover
It is not necessary to explain what is happening, just how to reproduce it.
2016-12-18SCI32: Add workaround for bad kArraySetElements call at end of Phant1Colin Snover

2016-10-15SCI32: Fix crash in LSL6hires endingColin Snover
Fixes Trac#9613.
2016-10-12SCI: Add modified workaround for Simbani bridge room for GOGWillem Jan Palenstijn
The GOG version comes with a fan patch that uses rm470::name to store a timer to rate-limit rm470::doit. This breaks the workaround detection since that uses the name field.
2016-10-05SCI32: Fix uninitialized read when starting a new game in LSL6hiresColin Snover
2016-10-01SCI32: Fix crash when trying to interrogate bartender in GK1Colin Snover
2016-09-29SCI32: Add workaround for kNumCelsColin Snover
This workaround may be able to be vastly simplified in the future since, so far, simply returning the number of cels in loop 0 is enough to make all the scripts with this bug work as expected.
2016-09-29SCI32: Fix SQ6 crash using the special button in Stooge Fighter 3Colin Snover
2016-09-29SCI32: Improve MGDX supportColin Snover
Audio directory switching is temporarily disabled because it causes use-after-free in the resource manager.
2016-09-29SCI32: Fix kFileIOOpen signatureColin Snover
The mode argument is required in SCI32 too; Torin just had a script bug.
2016-09-29SCI32: Rewrite kArray & kStringColin Snover
This change invalidates earlier SCI32 save games, which separated arrays and strings in an incompatible manner. Old save games contain invalid references to a string segment which no longer exists, and contain incompatible array structures that lack critical type information.
2016-09-29SCI: Generalize code for getting information on the current callColin Snover
