r42205 | dreammaster | 2009-07-07 17:41:02 +1000 (Tue, 07 Jul 2009) | 1 line
Removed the shooting workaround delay - the overlay number can vary, so it isn't a reliable way of identifying the specific message
........
r42206 | thebluegr | 2009-07-07 17:44:25 +1000 (Tue, 07 Jul 2009) | 4 lines
- Added auto-detection for EGA graphics. As a result of this, GF_SCI1_EGA has been removed and versions SCI_VERSION_01_EGA and SCI_VERSION_01_VGA have been merged into SCI_VERSION_01
- Simplified the checks for EGA and VGA graphics
- Fixed a bug in script_adjust_opcode_formats()
- Simplified the code in GfxResManager::getView() a bit

Add detection of Playtoons 2 En
........
r42209 | thebluegr | 2009-07-07 17:51:26 +1000 (Tue, 07 Jul 2009) | 1 line
Added a SCI1.1 case in the lofss opcode, like in the lofsa opcode (essentially, lofss and lofsa both load an offset, with lofsa loading it in the accumulator and lofss in the stack). lofss is rarely used in SCI1.1 games, which explains why no lofss-related crashes have been observed in SCI1.1
........
r42211 | thebluegr | 2009-07-07 20:28:05 +1000 (Tue, 07 Jul 2009) | 1 line
Added auto-detection for games with older headers for script blocks, and removed game flag GF_SCI0_OLD
........
r42212 | thebluegr | 2009-07-07 21:14:18 +1000 (Tue, 07 Jul 2009) | 1 line
Cleanup: added an enum for the auto-detected features, removed the selectors which are only used for auto-detection from the convenience selector map and placed feature auto-detection in a separate function. Also, now the automatically detected graphics resources are shown in the console.
........
r42214 | strangerke | 2009-07-07 21:58:22 +1000 (Tue, 07 Jul 2009) | 2 lines
- Separate Playtoons gametypes from in GobEngine::initGameParts()
- Add a specific save/load class for Playtoons as some specific files need to be tested
........
r42215 | strangerke | 2009-07-07 22:03:27 +1000 (Tue, 07 Jul 2009) | 3 lines
- Add a new gametype for 'The Land of the Magic Stones'
- Add detection of the french version
- Add a new game feature for 800*600
........
r42216 | thebluegr | 2009-07-07 22:29:55 +1000 (Tue, 07 Jul 2009) | 1 line
Removed the superfluous sci_version_types array (it's essentially the same as the versionNames array)
........
r42217 | strangerke | 2009-07-07 22:51:21 +1000 (Tue, 07 Jul 2009) | 1 line
Change SaveLoad_Playtoons case
........
r42219 | thebluegr | 2009-07-07 23:39:24 +1000 (Tue, 07 Jul 2009) | 1 line
Removed the weird checks for a maximum resource number (the sci_max_resource_nr array), as it doesn't serve any real purpose and leads to strange errors: if a resource is found which is bigger than the maximum number, it will be remapped to an incorrect number from this check. This makes KQ5CD work properly again (resources would be remapped to incorrect resource numbers from this code as a result of not updating this array with the latest SCI version merges).
........
r42221 | lordhoto | 2009-07-08 00:22:23 +1000 (Wed, 08 Jul 2009) | 1 line
Add generic functionallity to draw FM-Towns ROM. (To be used by KYRA and SCI)
........
r42222 | lordhoto | 2009-07-08 00:22:39 +1000 (Wed, 08 Jul 2009) | 1 line
Adapt KYRA to use the new Graphics::FontSJIS code.
........
r42229 | sev | 2009-07-08 03:11:29 +1000 (Wed, 08 Jul 2009) | 2 lines
kFeatures800 -> kFeatures800x600 in order to have more meaningful name
........
r42230 | lordhoto | 2009-07-08 04:10:35 +1000 (Wed, 08 Jul 2009) | 2 lines
- Added support for outlined FM-Towns ROM drawing
- Adapted KYRA to use that
........
r42231 | lordhoto | 2009-07-08 04:17:30 +1000 (Wed, 08 Jul 2009) | 2 lines
- Rename FontSJIS::enableShadow to enableOutline.
- Initialize outline to false by default in FontTowns.
........
r42232 | lordhoto | 2009-07-08 05:00:39 +1000 (Wed, 08 Jul 2009) | 1 line
Change "FM-Towns" to "FM-TOWNS" for consistency.
........
r42233 | lordhoto | 2009-07-08 05:00:51 +1000 (Wed, 08 Jul 2009) | 1 line
Add guards to only include SJIS font code, when KYRA or SCI is enabled.
........
r42234 | lordhoto | 2009-07-08 05:18:32 +1000 (Wed, 08 Jul 2009) | 1 line
Simply compile guard of SJIS code and fix comment.
........
r42235 | lordhoto | 2009-07-08 05:18:53 +1000 (Wed, 08 Jul 2009) | 1 line
Change all uses of FM-Towns/fm-towns to FM-TOWNS.
........
r42238 | thebluegr | 2009-07-08 06:01:15 +1000 (Wed, 08 Jul 2009) | 1 line
Added a workaround for incorrect font references in LSL1VGA (which was the original purpose of the code removed in rev. 42219)
........
r42239 | thebluegr | 2009-07-08 06:17:07 +1000 (Wed, 08 Jul 2009) | 1 line
Improved the LSL1VGA workaround after talking with waltervn
........
r42240 | thebluegr | 2009-07-08 06:43:27 +1000 (Wed, 08 Jul 2009) | 1 line
Silenced the very chatty song iterator console messages by converting them to appropriate debug messages
