Wait you want to fit floating point data into 2 bytes of space? o.O There is barely enough space there for any accuracy at all

Indeed it would seem so, anyways back on topic Can't wait to see more progress ^^

How do I put parts of a code as an appvar?

This is extremely difficult to get working, because of the way assembly works.  Assembly code only works at a specific location, if it is moved to anywhere else in memory, it will cause horrible crashes.  The issue with running code in an appvar, is that you need to copy that code to $959D, which is where your current program is!  It becomes a bit easier if your current program is an appvar, but even then it requires custom asm and Bcall knowledge.  I am not an expert on getting it to work, so I can't provide the details.  So the most I can say is try to fit all your code in 1 program, and use a program like Fullrene or Crabcake to surpass the execution limits. 

NO NO NO, lol, is your program compiled in noshell? If so then on wabbit emu, you need noshell to run it. so in order to play robogun on wabbit, you must download noshell on to it.

Saintrunner calm down.  He is correct, if you compile a program under the option No Shell, you do not need the program no-shell to run it.  All no-shell does is allow you to run programs without going to Mirage, Doors, Ion, or using the Asm() command.

And yes Epic, if your program is over 8100 bytes, you will not be able to run it from the homescreen with Asm().  You need to run it using a shell.  However, if your executable is over 8800 bytes, it cannot run as a program at all without a library like Fullrene or Crabcake, or needs to be an application. 

      So I was messing around with minecarts in Minecraft today, and I noticed something strange.  I had put about a dozen minecarts on a single track, and whenever they got closer to each other, every once in a while my player would move slightly.  Intrigued, I began to test.  I build a 2x2 circle of rails, and added in several dozen minecarts.  The results were interesting for sure.  My player would be pushed away from the spinning minecarts with a surprising amount of force.  What's more, any attempt to break a nearby block did nothing.  I ended up building a facility to test this phenomenon.  It has a bank of 114 minecarts that can slowly be added into a central field generator, and nearby minecarts to test the fields strength.  Check it out!

Here is a picture featuring the field generator

The tilemapper looks very well done, are you redrawing the screen every frame or using some sort of tricky shifting?  Eager to see your approach on enemies and how the towers function ^^

What would an uppercase E look like if it was only 4 tall? o.O
