SuperLemminiToo v1.01 2021-Oct-08

This is SuperLemminiToo: a fork of SuperLemmini, which is itself a fork of Lemmini.
I made this because there were some minor features I wanted to see in SuperLemmini, which didn't appear to be in the original author's immediate timeline.
I'm not really taking requests, but I'm releasing because I figure some other users may want the same features I did.

==USAGE===========

SuperLemminiToo uses the same ini file as SuperLemmini. You can extract this program to its own folder and it will read in all your existing settings from SuperLemmini.

You will need Java 15 or higher.

==FEATURES========

The main feature I wanted to restore was Timed Bombers. Not everybody shares this desire (which is why the feature is selectable, under Options), but I feel strongly that in *ORIGINAL* lemmings levels, it is 100% intentional that you need to use a blocker then a bomber if you want to have precise placement of your bombers. Look no further than "Fun 6: A task for blockers and bombers" for proof.
I felt so strongly about it, in fact, that I created this fork.  Everything else changed was just extras once I started looking under the hood.

I unlocked all levels. Also a toggable option.
In SuperLemmini this was considered a "cheat" that was enabled with a secret level code.  The "cheat" code also enabled a bunch of special debug features, which I didn't want.  I figure the game's about having fun, so why shouldn't people be able to skip a level they're having difficulty with. Who's to tell them no?
The game still keeps track of levels you've completed or not, so it's still up to you if you want to complete every level.

Added "Disable Scroll Wheel" option. 
I found it annoying how my scroll wheel would accidentally change my selected skill when I was trying to middle click.

Added "Disable Frame Stepping" option.
Here's where I really started to get a bit nit-picky.
When paused, if you click anywhere, the game will advance by one frame. Didn't like that feature, so I made it togglable.

Minor feature, I added some ToolTips to the checkboxes in the Options dialog. I wasn't exactly sure what some options meant at first glance.

I also upgraded Java to 15, instead of 1.8. Java 15 adds some better HiDPI support, vs 1.8, which was a must for me.  Java 15's a bit harder to install... it's not at java.com (that's only version 1.8).  It might be called Oracle Java, or Java SE. I'm not sure the difference between all the Java versions you'll see. You'll need to install 15 or higher. I used 17:

==THANKS==========

I want to stress that this program was truly written by Volker Oth (Lemmini) and Ryan Sakowski (SuperLemmini), over a combined total of more than twenty years. All I've done is hack a couple lines of code. None of this could be possible without the literally thousands of hours of work done by those two individuals, and their making the source code freely available. Thansk you both for letting me re-live some joy from my childhood in a new way, and for letting me share it with my kids.

Also special thanks to WillLem from the LemmingsForums.net for providing the updated title graphic, and being all around supportive of this endeavour and SuperLemmini in particular.

==KNOWN ISSUES====

I've read (but not tested) that Java 15 produces different png files than Java 1.8, so if you've never used SuperLemmini before and need to extract the resources from Lemmings 95 (aka WinLemm), you'll need to do that through the original SuperLemmini.  Then once that's done, you can continue with SuperLemminiToo.

I didn't test anything related to Replays and External levels, as those didn't personally interest me.
