Hmm, this is odd...

I sent both the program and data file for Space Shootout to my calculator, and tried to run them in PreOS, but it simply does nothing and immdiately returns to the kernel after displaying "Extracting..." in the status line. I tried archiving and unarchiving the files, but to no avail. Does anybody know what's wrong?

hello, how much free memory do you have? if you dont have enough a mem error will appear very briefly in the status line.

and don't worry guys - im going to convert SSO to nostub like people have been asking, and it will be version 1.01 since people have been saying its too easy. well 1.01 will be:
nostub
harder

Please try to add TI92+/V200 support too :)
Your game looks nice and i can't play it on my calc

sure i'll try since i think its only two lines of code, but i cant test them since vti emulates ti89.. so i'll email them to somebody who has a one of those calcs... and if they work.. then ill submit them.

I KNOW it's illegal (don't start another of those stupid debates) but you COULD download a 92+ OS from the TI website and use it with VTI to test your program...

And as far as I know, TI doesn't really care about developers owning one TI-68k calculator and emulating another for testing their programs. They have even sent ROMs out to people explicitly stating that as the purpose. But if you are paranoid, you can always use the TI-92+ version of PedroM on VTI.

Actually, the ROMs you download from TI's website don't work directly with VTI. You need to get the ROM image from a real calc.

The ROM updates from TI's website _do_ work with VTI.

What? Is there some new version of VTI that accepts .89u files?

I've done it with VTI 2.5b. It automatically detects them as ROMs, I guess.

E-mail me.

Also...looking from the screenshots, I noticed that you spelled "triple" incorrectly. You spelled it as "tripple"

-Not trying to be negative, I am not W-

hello: as i mentioned earlier, i was going to convert SSO to nostub - and i have. the bad news is, the nostub version has a serious error. Here is what i did:
i fixed the spelling error in the shop. made the prices higher. made enemies health higher for each level except the first. and i made the bullets you shoot move up faster. THATS ALL. now if you run it, and after the first enemy appears (first level) if you exit and rerun exit crashes. If you exit before the first enemies appear you CAN rerun. if you skip the first level and play 2-4 and exit, you CAN rerun, but if you see any enemies from level 5 or 1 the game CANNOT be rerun. this glitch makes absolutely no sense to me, since the enemies are the same variables in each level- just different sprites, routines and bullets! not to mention that it worked fine as a kernel program- AND i didn’t even do any modifications to the enemies in the first level!

i get the following errors on re-run:
errors with black bar at top of screen
-Privilege Violation
-Address Error
-Illegal Instruction

Tios window msg errors:
-Protected Memory Violation
-Unknown ERROR Code

it looks like a memory problem, but i don’t use malloc, and LCD_BUFF creates a buffer that i do not need to free. so it looks like the nostub version is delayed for 1)unknown time, 2)ever, 3)if someone knows how fix that! and the errors seem pretty random as to wich one ill get. also this version should work on 92p\v200

Archive both Preos and stdlib.
