The Lost World - Jurassic Park (c) 1997 Sega.

If you have a good arm at shooting games you're fine. But if you don't have a good arm at shooting games better start practicing, because half of the whole game you'll be shooting a lot of raptors coming at you 30 miles per hour!!!

Information on lostwsga

0.89u1 [Ville Linde, Andrew Gardner, R. Belmont]


- The ingame part of the game has an annoying raster pattern on top of everything. Keys Y to O are assigned as 2D layer toggle keys. Press U to disable layer 2 in Lost World. Also remember to calibrate the light gun in the test menu.


- 0.151: ShouTime corrected rom names and revision levels for The Lost World. Changed description to 'The Lost World (Revision A)'.

- 0.126: Removed mirrored region sound1 ($200000, 600000).

- 0.90u2: Changed PPC603 CPU1 clock speed to 100MHz. Added Light gun, 2x buttons and 2nd coin slot. Added region sound1 ($400000, 600000).

- 1st January 2005: Ville Linde - Let's start this year with something special... Wireframe for Lost World. Update: Added Z-buffering and texturing (no perspective correction or bilinear filtering yet).

- 0.89u3: Ville Linde added preliminary 53c810 SCSI emulation. Lost World now tries to download everything necessary to the Real3D stuff.

- 0.89u1: Added The Lost World (Sega 1997). Some basic 2D hooked up, nothing more.
