I don't know if someone notices, but there's a new version of Dosbox: 0.70
With this Dosbox, I tested playing Lemmings with the High Performance PCs option and it works great!
There's however a little problem with the color palette on the level presentation screen and a little bit in the skill menu, but the game is still fully playable. Same thing for any other Dos Lemmings games.
Also, LemEdit works GREAT under Dosbox 0.70! Use LemEdit3. No lag at all!
Lemmings 3 is now fully operationnal without any bugs!
ENJOOOOY!!!
