Developing a new and faster GMP compressor (for PC and PSX)
Hi!
After successfully convert the PSX maps to PC, I wondered if I can do that backwards, i.e. converting PC maps from DMA map editor into PSX readable maps. To achieve that goal, I needed to create my own GMP compressor, which was what I did.

I've found the address 0x5EAD76 in 9.6f or 11.44 which stores the boolean value (1 byte) for displaying names. Here is an example of toggling on/off displaying player names dynamically:

I've encountered another problem.
For Industrial map size a lot of objects required summary, approximately 2000-5000.
Tried to add 1000 trashcans with random XY-coords. Game can't start, crashes upon level loading.
Reduced amount of bins to 300, the game lasts 1 min 34 sec, then crashes.

Re: GMP rotator - Rotate your map by 90°, 180° or 270°
This could be a problem with traffic lights.
If you change map 90 or 270 degrees, originally horisontal layout made for 4:3 screen ratio will fit closer horisontally, and could cause 2 traffic lights to be seen that were originally not.
Traffic light zones must be at least a screen away ...

Re: GMP rotator - Rotate your map by 90°, 180° or 270°
I know the "blockd" param stores the block indexes of a column in DMAP and CMAP when compressing the map using map editor, but the "blockd" param in PSX gmp files seems to be different. My code now can read correctly CMAPs created by map editor, as well as DMAPs, but I'm struggling to read PSX maps ...

does gta2 map editor not load cmap and dmap?
So.. compressed cmap is basically 256 * 256 16 bit lookup table of columns (called base)
followed by 16 bit nuber of all columns structures
followed by column structures of varying lengths. and then table of blocks
base is lookup into columns and ...

GMP rotator/flipper - Flip or rotate your map by 90°, 180° or 270°
Hi!
I'm developing a GMP rotator/flipper. It already rotates/flips:
- Block positions
- Block tile lids
- Block tile sides
- All types of slopes
- Road arrows (green & red) & field arrows (for trains)
- Light coordinates
- Zone coordinates
The source code is here: https://github.com/Valps/gta2 ...
