Most likely. Try using Celtic III instead.

yeah the compatibily issues are annoying sometimes. Some games like XXR and Metroid II will run not too bad, but others will mess up very badly.

One issue is that certain xLIB games abuses xLIB bugs and glitches to perform some special effects. These glitches are not all emulated in Celtic III.

The only solution is to downgrade to OS 2.43, which you have to google or download from french TI sites such as TI-BANK

Even Omnicalc messes up sometimes in 2.53MP. I also had issues with anything using reverse text (white fonts on black)

I even heard stories about some new OS functions being buggy, even wehn you have absolutely no ASM program installed

They most likely released it to combat All the third party OS's in development.

There aren't any finished, but TI knows the community is up for something. Don't you find ironic that a new Nspire OS came out the week after the exploit was released?

I think people such as Brandon Wilson are working on new OSes, but I think the community looks more forward for trying to patches the issues in the ones TI release, since this would be much less work.

As for bugs, this is not new. TI calcs had bugs since the day the TI-81 came out. On the 83 and 83+ (early OSes) it was possible to crash the calc through an Equ>String bug. On 83+ OS 1.13, by scrolling the prgm menu with 50+ programs, the RAM cleared. I heard stories about Nspire OS bugs causing reboots. Finally, the classic memory leak in TI-BASIC caused by using a Goto inside a loop/condition block.

There is a topic listing glitches for TI-83+ and 84+ OSes from 1.12 to 2.43 at http://ourl.ca/3687

ah ok well try to not cause anything bad

The farthest I went is decreasing their contrast or installing fake viruses on their calc. Just make sure they have nothing important on their calc first, and I recommend against the group glitch and the equ>str one. They are very dangerous and could damage the calc.

WAIT! I wish I had a prog like this back when I coded The Reign Of Legends series. In these games, we had poor asm libs compared to xLIB and Celtic III, and we had to archive/unarchive a lot to fit the game on calc. However, this caused GC's, and sometimes we smashed enter too fast, and it exited the game with ERR:ARCHIVE FULL. Didn't save progress and got pissed. A program to force garbage collections every few battle would have been very handy.

However, today it wouldn't be as useful anymore to many people since the old method of archiving/unarchiving has been obsoleted by xLIB prgm copy functions (copying programs from archive to temporary RAM files)

Anyway back on topic, I hope BrandonW or someone will release a patch to fix all the compatibility issues in 2.53 MP. Mapar007 did a patch for 2.43 to disable the teacher feature to lock down the PRGM menu on 84+ calcs.

aaah ok I see. Thanks for the info

Btw, do you know if it's possible to change the garbage collect message or show none at all? For example, in a game like ROL3, I have a menu option to garbage collect manually, but it would have been cool for example if it automatically did it then right before I launch the command, I display "Reorganizing Archive Memory, this may take up to 1 minutes". Newbies, including myself back in 2001, can be scared when seeing the name Garbage Collect. By seeing Garbage, they may think if they choose yes, that their memory will be cleared. In french, TI fixed this by translating Garbage Collect to Reorganize Mem.
