Title: ASM Incompatibility between the TI84+ and TI83+?
Post by: CalcMax on January 14, 2017, 11:08:17 am
Would someone explain why TI83+ ASM programs like Maze 3D II(http://www.ticalc.org/archives/files/fileinfo/272/27287.html) , TI Linux,etc... Have issues on my revision M TI84+SE. This has annoyed me alot and I hope it can be fixed for once...  Best case is if it just slants the image or even twists it, and worst case is total or near total instability or even not wanting to run at all (freezes calc).
Best regards,
CalcMax

Have you run LCD fix (http://www.ticalc.org/archives/files/fileinfo/366/36608.html)?

No, I thought that program was needed only on the TI-83+. What causes these issues anyway?

UPDATE: I downloaded this fixer and now the problematic games work WITHOUT problems. Thanks alot!!!!!! I am hoping to one day find out what the hell causes this (detailed answer with all info you know, please...).

According to the description it is not for the 83+ it is only for the 83+SE, 84+, and 84+SE

This is a LCD driver fix for the 83+SE, 84+, and the 84+SE. This correct display problems that have been occuring in new model calculators. You see these problems in games like Fall Down, Desolate, Doom, and others. This fix is not for 83+, Sorry.
I'm glad it fixed things for you, as for why it did, I would recommend reading the readme: http://www.ticalc.org/cgi-bin/zipview?83plus/asm/programs/alcdfix.zip;Readme.txt

Some of the 83/84 have crappy lcd drivers with different amounts of delays.
The program is probably trying to write to the lcd before it is ready, so that byte isn't written at all and the byte after it takes its place.
I'm not sure how lcd fix does it, but it definitely does help.
I guess it is like having a game for the 84+ that is designed to run at 15MHz being forced to run a 6MHz on an 83+. It is bound to cause problems.

Hope that helped!
