hmm okay dysfunction was always wondering why map loading took so long in Diortem and Metroid II (between 1 and 4 seconds), well before you continue reading, I must warn you: the code below may be offensive to BASIC programmers, because there is so many things that are done at map loading that after a while the code went so messy that it now reminds me my old days of Illusiat (without the Lbl/gotos) O_O

:knight:

and I got headache reading it. Btw this is one of the reason why Diortem died the first time, I gave up on this code. Now i rewriten most of it before finishing metriod but still... I was wondering if there would be some stuff that could be made more optimized in this mess >.

It's not offensive but it confused the heck out of me - I just looked at the first few lines and my brain went:

Well, you can and not only that but Finance Vars are not only faster then normal Vars but faster then Ans as well, which is the reason I use them in anything that needs to have an ubsurly high screen refresh rate.

ok I guess I'll try to use those instead of A and B for character moving then if i make a new game :P

Well they can't be deleted like with A-theta and they take up one extra byte I believe.

you mean, token wise? (as some tokens takes 2 bytes instead of 1)

yeah I know you are talking about those, but when pasting for example "PMT" in a program does it takes 2 bytes instead of 1? Like lowercase letters? Also technically we cant even delete a finance var, as it will be set back to 0 so it will always take space

Lets go over the advantages and disadvantages.

Advantages:
-Fastest

Disadvantages:
-Can't use with DeleteVar or for(
-2 bytes rather then one.

So I will say this: it is not always the best choice of variable, but is a nice thing to know that it can be used if needed.

Ok, I finished optimizing it. Is this just a program in M2E? I need to test something, as I think I can save a few more bytes. As of now I got it down about 4xxbytes.
