The Lost World with MAME .270

Recommended Posts

Sorry if this is not the correct place to post this. I have been setting up my LB to be able to make it portable. I have figured out all of my issues besides one. I have a Sinden light gun ordered and after watching some videos on the top light gun games I am interested in playing Jurassic Park the lost world. I have the zipped folder in my complete merged rom set 0.270 and the zipped folders name is jplstw22. I manually imported the game after it did not show up in LB and unchecked all of the places that would prevent a particular type of game from importing. I now see the game in LB however when I try to run the game is does not work. I did verify the file name it is looking for matches the folder name I posted. I tried to use MAME outside of LB to open it and I do not know if it I did it correctly but it still will not work. Is this simply an issue with the rom file or something else. I have an older rom set from a year or so ago and it also does not work on another machine with LB  installed. Thank you

jplstw22.zip didn't import because it's for a 'Mechanical' Pinball machine (but sounds like you eventually un-checked Skip Mechanical Games).  And for that same reason, it unplayable in MAME.

For The Lost World: Jurassic Park, the ROM (in your full set) you're looking for is lostwsga.zip.  But using the MAME Arcade Import Wizard, that won't import either because it's Unplayable in MAME (unless of course you un-check Skip Games That are Unplayable).

The emulator you want to use for that game is Supermodel (a Sega Model 3 emulator).  You will also need the Device file segabill.zip (also found in your full set).
