Lemmings Main / please help me with a test on timing
« on: August 05, 2006, 09:54:23 AM »
I'm performing some tests to work out exactly how much time the game really gives you, down to the frame level.̆ However, currently my only means of running Lemmings is through DOSBox, and I'm not always sure whether it emulates some aspects of Lemmings well enough to trust it for perfect timing (particularly I'm uncertain about the fade-in/fade-out aspect).
So I'm hoping someone out here can try this out on a machine that can run Lemmings in DOS mode, without DOSBox.̆ This means it has to be a Windows 95/98/ME machine (or, if you actually still have MS-DOS, that), preferably a desktop machine.̆ I copied some instructions from Microsoft's Help and Support (actually I Googled to get there) for setting up a program to be run in MS-DOS mode:
1. Right-click the program's executable (.exe) file or its .pif file, and then click Properties.̆
2. Click the Program tab, and then click Advanced.̆
3. Click to select the MS-DOS Mode check box
(see http://support.microsoft.com/?id=188157 for further information if interested, not necessary)
Note that MS-DOS mode means Windows will shut down, then restart the machine in a DOS-like setup to run your program (Lemmings in this case).̆ When the program quits the machine will again restart and reload Windows.

The test to try out is either one of the following custom levels (in LVL format):
http://www.geocities.com/guestlevels/lemmings/timelem.zip
http://www.geocities.com/guestlevels/lemmings/timeonml.zip
To test original DOS Lemmings (the very original where vgalemmi.exe is only around 32KB or so), use timelem.zip.̆ To test other versions (ONML, CustLemm, non-original DOS Lemmings etc.) use timeonml.zip.̆ I don't know which version of the level is appropriate for the various Xmas Lemmings games so don't bother with those for now.
It's designed to be an exceedingly boring level.̆ You don't have to do anything.̆ In fact, please do not pause the game when "playing" the level.̆ Just let it run on its own until times up (it's a one-minute level).̆ You can scroll around the level if you feel like but as I said, it's boring.
The main thing we are testing is the % saved reported by the game once the level times out.̆ In DOSBox, I get 25% with the game in "PC compatible" machine mode (the default option that most people uses when runing Lemmings).̆ Do you get the same result in real DOS?
For fun, I'm also curious whether the numbers are different in real DOS if you use the other three modes, particularly "High Performance".̆ That mode doesn't even work in DOSBox.̆ I did try the PS/2 mode in DOSBox and it turns out due to the noticeably slower fade-in/fade-out, you get noticeably a bit more time and so 100% is easily achievable.̆ But then again DOSBox aren't using the correct colors when emulating PS/2-mode Lemmings, so maybe the fade-out is not at the correct speed either for all I know.̆ The Amstrad mode seems to behave exactly the same as PC compatible in DOSBox, with the same save percentage results.
Thanks in advance!
