2016-02-28AGI: Fix small memory leak in Hercules font loaderTorbjörn Andersson
2016-02-28AGI: Set monitor VM var to EGA for Hercules renderingMartin Kiewitz
Original AGI Hercules rendering was restricted by the Hercules resolution, which is why they had to remove the AGI prompt and replace it with a prompt window like the one used in SCI. We are not and even when we support that prompt window, we will still support the original AGI prompt even for Hercules rendering. Maybe some games had special graphic code, when Hercules rendering is active. This needs to get checked. We are now telling the scripts that we are running on EGA, so that they don't put text at different coordinates. Hercules rendering also used a different grid for putting text for example Space Quest 2 right at the start. This change avoids problems with such placement. We don't really want to restrict ourselves by implementing that different text grid resolution. Also added comments on game feature flags.
2016-02-28AGI: Disable font loading from HGC_GRAF.OVL (AGI3)Martin Kiewitz
It seems Sierra basically put a low res font in there, so it's useless. We should rather directly use the PC BIOS font in those cases. The code could be useful at some point in case we add support for the AGI3 Hercules rendering, although I think it looks worse, because graphics are basically "compressed".
2016-02-28AGI: Hercules rendering for game screenMartin Kiewitz
2016-02-27AGI: Add support for upscaling and Hercules hires fontMartin Kiewitz
- User option to force Hercules hires font for any rendering mode - Also change mouse cursor hotspots from 1,1 to 0,0 - Fix inaccuracy in mouse controlled game menu - Change render_Block(), drawBox(), drawDisplayRect() to use upper Y instead of lower Y. Original AGI uses lower Y, but upper Y makes upscaling way easier.

2016-02-25AGI: Add detection for 13th Disciple 1.01 bug #7010Martin Kiewitz
2016-02-20AGI: Add detection for fan games with broken volume bug #7035Martin Kiewitz
Plenty of fan games set volume to mute, because they thought 15 would be loudest. It's in fact "mute" in AGI. Those games were made primarily for PC AGI, which did not use the volume setting. We do, so such games would get muted audio. We try to detect such games. Hopefully fully fixes bug #7035. Too many games to try them all out.
2016-02-20AGI: Added comments about Black Cauldron+KQ2, removed warningMartin Kiewitz
Also removed old comments about testing needed for IIgs Also removed warning when game speed is overwritten for IIgs, b/c all games were tested and should run properly now.
2016-02-19AGI: Comment about another artificial delay situationMartin Kiewitz
Gold Rush, Stagecoach path, after solving steep hill
2016-02-19AGI: Fix a tiny inaccuracy in string word wrapperMartin Kiewitz
Fixes one message box in Gold Rush during Stagecoach path, that wasn't wrapped correctly.
2016-02-19AGI: Add artificial delay for GR stagecoach pathMartin Kiewitz
2016-02-19AGI: Slightly change artificial delay to detect GR muleMartin Kiewitz
Now also detects the text, that is shown when following your mule in Gold Rush!
2016-02-19AGI: Fix comment about end.of.loop/motionMartin Kiewitz
2016-02-19AGI: Add detection+workaround for endofloop+motion at the same timeMartin Kiewitz
Detects when end.of.loop + motions are used on the same screen object at the same time, which would have resulted in flag corruption in the original interpreter. We detect this situation now, show a warning and disable the cycler in case cycler was activated first. This solves a new issue in kq1, when grabbing the eagle in room 22, that was previously hidden just like in the original AGI. Fixes bug #7046
2016-02-19AGI: Save screen object loop_flagMartin Kiewitz
loop_flag was previously vt.parm1, which was shared for multiple uses. Was split up during graphics rewrite in commit 8a595e7771aa89d06876e13d7ab6751e26da8982 Is indirectly part of bug #7046. Saving, restarting ScummVM and restoring right after grabbing the eagle resulted in the glitch not happening (which was of course an inaccuracy anyway). This was caused by AGI currently not saving/restoring the loop_flag. Needs to get further figured out what's exactly happening internally and if this issue was just hidden by the shared vt.parm1 in previous versions. If triggered, it would have just set another pseudo-random flag on end-of-loop.
2016-02-18AGI: Add missed commaEugene Sandulenko
2016-02-18AGI: Apple IIgs time delay override MH1 completedMartin Kiewitz
+ Disable hide.mouse for MH1 Apple IIgs
2016-02-18AGI: Apple IIgs time delay override KQ4 completedMartin Kiewitz
2016-02-17AGI: Make SQ2 Apple IIgs get a AGI 2.917 equivalent and not 2.936Martin Kiewitz
Solves the priority issues at the end, because the set.pri.base call is now rejected by us. The IIgs interpreter seems to feature 177 kernel calls, but the last few are not what we expect them to be. It seems set.pri.base was discard.sound for this interpreter. It seems it was cleaned up for kq4. That one actually uses dynamic priority bands and it's working properly. Fixes bug #7034
2016-02-16AGI: Added comment about artificial delay sq2 sceneMartin Kiewitz
2016-02-16AGI: Set.pri.base comments added (Apple IIgs KQ3+SQ2)Martin Kiewitz
For KQ3 the calls are currently blocked b/c interpreter version For SQ2 they aren't, which causes a few priority issues at the end
2016-02-16AGI: Added console command to disable automatic savesMartin Kiewitz
Helps creating various saved games for Mixed Up Mother Goose
2016-02-16AGI: Change how VM timer vars are handledMartin Kiewitz
Instead of directly converting play time to VM timer vars, we only adjust VM timer vars according to play time seconds delta. This is needed for at least Mixed Up Mother Goose. The game sets the VM "second" variable to 0 and then uses it for syncing the text to the songs. We even adjust second calculation, so that the timing should always be the same and not depend on basically luck (seconds may wrap right after setting it, because internal cycles counter is not changed).
2016-02-14AGI: Changes to vm var seconds heuristic (delay loop detection)Martin Kiewitz
- small fix (forgot to reset the hit counter) - rename methods - added more information about PQ1 in comment
2016-02-14AGI: Add heuristic to detect delay loops within scriptsMartin Kiewitz
And in that case poll events, delay for a few milliseconds and update screen. This somewhat worked before the graphics rewrite because of a timer hack. This one tries to detect actual inner loops. Happens in at least Police Quest 1 when playing poker.
2016-02-14AGI: Added a few comments about KQ1Martin Kiewitz
set.simple gets called when killing the witch + planting beans Right after bowing to the king, ego faces away from him. This issue was already present in 1.7.0. Could probably get solved later via script patcher.
2016-02-14AGI: Fix another comment about dynamic priority tableMartin Kiewitz
Available also in 2.425, then removed until 2.936, yada yada. priorityToY-Glitch is definitely present in 2.425 as well.
2016-02-14AGI: set.pri.base was actually available in AGI2.425Martin Kiewitz
Was available only in 2.425 and in 2.936+. Fixing comment accordingly. Also allowing the command for 2.425.
2016-02-13AGI: Fix new createDefaultPriorityTable() codeMartin Kiewitz
2016-02-13AGI: Fix priority band handlingMartin Kiewitz
- Fix saving/loading priority bands table. Now saving the actual raw data - Now also saving the flag, that defines if the priority table got modified by scripts - For older saved games it will try to figure out the state of that flag - Blocking set.pri.base for AGI below 2.936 - set.pri.base was actually introduced in 2.936 and not AGI3 - The set.pri.base bug was present in 2.936 as well - Saved games created between the graphics rewrite and this commit may have priority issues for games, that used AGI2.936+
2016-02-13AGI: Add another situation that needs artificial delayMartin Kiewitz
Comment only SQ1, right at the end of the asteroids
2016-02-13AGI: Apple IIgs time delay override SQ1 completedMartin Kiewitz
2016-02-13AGI: Adding seconds of current time to saved gamesMartin Kiewitz
Useful to properly detect the most recent saved game (that's done by the original save/restore dialogs)
2016-02-13AGI: Apple IIgs time delay override KQ4 data addedMartin Kiewitz
2016-02-13AGI: Apple IIgs time delay override SQ2 data addedMartin Kiewitz
2016-02-13AGI: Add time delay overwrite for AppleIIgsMartin Kiewitz
Should somewhat fix bug #7026 Needs testing (although AGI games need to get tested for 1.8.0 anyway)
2016-02-11AGI: Rename nonBlockingText -> artificialDelayMartin Kiewitz
Also add a table for Apple IIgs games for music issues like in PQ1 intro, where the developers thought that loading a new room would take X amount of time and they started loading before the music was done. In our AGI music may get cut off because of this. It of course also happens, when using the original interpreter, as soon as you emulate a faster processor. Which means this is also a workaround. See bug #7026
2016-02-10AGI: Remove unused methodMartin Kiewitz
2016-02-10AGI: CleanupMartin Kiewitz
2016-02-10AGI: Init video before font + text initMartin Kiewitz
2016-02-09AGI: Use special Apple IIgs SQ1 palette for SQ1Martin Kiewitz
Was already documented inside palette.h, but wasn't used yet
2016-02-09AGI: Fix warningMartin Kiewitz
2016-02-09AGI: Fix invalid coordinate warnings for spritesMartin Kiewitz
2016-02-09AGI: Only set VAR_KEY,when no controller/directionMartin Kiewitz
Fixes Mixed Up Mother Goose Apple IIgs save/restore prompt
2016-02-09AGI: Hold-Key: only send stationary for directionsMartin Kiewitz
2016-02-09AGI: Fix skip auto-save slot code for auto-saveMartin Kiewitz
2016-02-09AGI: Check xPos/yPos when building sprite listsMartin Kiewitz
And ignore sprites, that are placed outside of visual screen Fixes memory corruption during intro of fan made Get Outta SQ game. Original AGI did not do checks at all.
2016-02-09AGI: Cut menu in case menu names are too longMartin Kiewitz
Required for games that add to many names or add names, that are too long. The code needs to get adjusted anyway for different platforms, so for now just cut the menu names instead Required for at least the fan game Get Outta Space Quest
2016-02-09AGI: Change set.simple string copy codeMartin Kiewitz
