 * All structs directly mapped to memory that are not trivially replaced (such as 'scen_animations'). Currently use (or should use - this is still WIP) READ_LE_* functions to read most member variables which are known to be in LE format and only read from - NOT written to. Later, when the data is hopefully converted to native format during loading, these READ_LE_* calls should obviously go.
-== Showstoppers/Overall bugs ==
+== Bugs ==
-* Currently only VGA floppy is supported so we should add MD5-based detection before it will go to CVS
+* It hangs on "please wait" screen in EGA version when screen is completed or switched by code
+* Keyboard input is buggy as some keypressed get ignored. Particularly noticeable when entering screen code
+* When game calls delay() screen doesn't get redrawn. Noticeable at "please wait" screen and especially cutscenes (try screen #5 FTWKFEN)
 * Demo doesn't handle last screen properly. It hangs instead of printing ordering info
-== More on Endianness and Alignment ==

-''I am going to work on this, this Sunday. I will initlally confine myself to game.cpp, and then start migrating the changes to wherever the files are accessed.''
-It crashes now in game.cpp function game_loadExtTable() at
-data_readData().
-This is all bad. Whole game tries to read structures directly without parsing them.
-Problems which it arises:
-* sizeof(struct) is bigger than sum of sizes of its elements on most systems due to alignment. This is why it crashes now
-* Endianness is not honoured
-What we should do here is get rid of both data_openData and data_readData()
-and write function with this prototype (give it proper name):
-   MemoryReadStream data_getData(const char *filename, const char *chunkname);
-It will read whole named chunk and return a stream of it. So code using it
-will look as follow:
-  chunk = new data_getData("intro.stk", "intro.tot");
-  foo.a = chunk.readUint32LE();
-  chunk.read(foo.b, 20);
-  delete chunk;
-MemoryReadStream will track end of chunk by itself, so no additional code is needed.
-All places should be revisited and rewritten as every one will cause problems.
-This will let us get rid of file_open() too which is an implementation of
-an ugly idea.
-==== Update ====
-''sev:'' As a temporary solution I fixed that with such code:
-  data_readData(game_extHandle, (char *)&game_extTable->items[i].offset, 4);
-  game_extTable->items[i].offset = FROM_LE_32(game_extTable->items[i].offset);
-  data_readData(game_extHandle, (char *)&game_extTable->items[i].size, 2);
-  game_extTable->items[i].size = FROM_LE_16(game_extTable->items[i].size);
-which is ugly, difficult to read but feasible until proper object-oriented implementation will be done

-* Add support for other rendering modes (EGA/CGA/Hercules) - the EGA version of Gobliiins works with gobreverse, so vid_spriteUncompressor needs to be adjusted and/or the packedSprite drawing routine from the driver need to be implemented.
