Hello, Triang3l. Your map converter is awesome but I have some problems with BSP to BS2 conversion. I don't know if you are aware of those issues, so I would just leave this list here:

1. Crashes on real PS2 (or red messages in PCSX2 "Program log" console). I found out that most of them are related to NPC movement. On start of first Half-life: Uplink map there are no crashes until Barney starts running to scientist or houndeye behind a door on the left is provoked.

2. Sometimes NPC's are unable to walk through their scripted path (Barney on anomalous materials entrance is not coming to open tram door, scientist can't walk through retractable bridge in the Blue Shift intro).

3. I don't know if it is normal, but BS2PC gives this error during conversion of Blue Shift map "ba_power2.bsp".
   

4. Texture fethching from some WAD's is broken. BS2PC just crashes during conversion if it tries to get textures from WAD.
   I performed a little investigation. Problem is in "bs2pc_wad.c" file. It starts when "mid" variable has zero value. It causes underflow of "high" variable and then "mid" and "low" are updated with enormous values that derived from "high".
   

It all ends with this exception.

Then I applied this quick hack, it allows to complete map conversion.

But there are still some checkerboarded textures in resulting map. Examples:

Face 1576 has -2 as its first surfedge which corresponds to a vertex that makes no sense for the face. I mucked around with the BSP and it seems like -4144 should correspond to the correct vertex but setting it causes the face to seemingly disappear and I don't know enough about the BSP format to know why. This issue occurs with the latest version of BS2PC and the version before the full rework.
