The safe fall distance is never really 60 in the original version (even on the Amiga). A0;It has nothing to do with hacking or not hacking. A0;It's basically a bug in how they track the falling distance, so that even though the game tries to look for the number 60, the calculation can be off causing slightly higher numbers to still pass the test.
It's true that supposedly some of the games uses the number 63 instead 60. A0;At least Mike seems to think that for ONML they purposely changed the distance to 63, even though on my copy it's still 60. A0;So as you can see, we don't even know at this point what the intended numbers are for all the different games.
Mike specified that it is supposed to be 60. Ok, I don't know myself if this safe-fall distance
apply to each version. But, I supposed that 60 is kinda an universal safe-fall distance. I mean, it could be weird to have a safe-fall distance of 70 in a game and a safe-fall distance of 50 in another one, even if it's only 3 of difference!
For the skills toolbar, this is less important. Much people uses Windows XP and plays Lemmings under Dosbox. But, yep: The toolbar disappear when playing the game under Windows only. Under Dosbox or under the plain Dos (in older versions of Windows), the toolbar now reappear.
How do you know that VERSIONNUM and CHAET CODE is universal for all these games you listed above? Doesn't ONML use SLAMRACING for example? You are assuming way too much about the universality of the cheat codes. Keep in mind that cheat codes are not meant to be an official feature of the game in the first place, there's no reason they have to work on every game, and there's certainly no reason they have to use the same one for all of them.
Still there I suppose that each game have both a cheat code and a version number code. The version number code is less important. In fact, if there's only one version of a game, just specify the title of the game, the date where it was made and the mention "Version 1.0" into. For the cheat code, I know that much of the games have one:
- Lemmings : BILLANDTED
- Oh no! More Lemmings : SLAMRACING
- All the Xmas and Holiday Lemmings : SNOWFLAKES (or, I would like to add this new one for the Holiday Lemmings (not the Xmas) : SANTACLAUS)
- Save the Lemmings and Lemmings Companion, just use the original Lemmings code : BILLANDTED
- Customized Lemmings : SKIPLEVELS
For the menu of selecting the type of PC, it could be so great to have the possibility to select "High Performance PCs" and that this works perfectly... maybe with the next version of Dosbox!
For the program, yeah, forget it!
