This port uses SDL2 instead of SDL1.2

Images of the port running on real hardware:

The previous attempt was also SDL2, the remaining issues was fully working sound ingame and being able to get to the dungeon on real hardware

I found another issue: the mappings of gamepad on ps2 doesn't work properly. The dungeon level doesn't load.

The dungeon level doesn't load.

For me the issue was caused by it failing to reading / writing the save file

It's not related since i could load my profile without any issue. I will see if there is a implementation on other platforms to fix that.

Your probably running out of memory, try disabling sound support with -DNOSOUND=ON that should save a lot of memory.

Using a custom PS2 audio and unpacked MPQ saves enough memory to run the game.

I will test the no sound option and if works i will revert the other commit that uses custom audio keeping audiolib working.

Updates: even with custom PS2 audio, the level doesn´t load also when i deactivate no sound for video it plays without sound due to a dependency of AudioLib. If we want the video audio working properly AudioLib should be enabled.
