At the moment, MAME 2003-Plus has more advanced support for analog input devices. It is currently in testing, although after about six weeks the new analog input features have been tested by a fair number of users.

2nd Advanded mame it works so much better with spinners. actually advanced mame is newer than Advanced mame 1.4 its 3.9.

@BuZz said in MAME 2003 "vector" games only displaying 1/4 of screen after updating - what needs to be edited?:

BTW the vector games did work on the last binary so it may have been a core option affecting this. there has been some fixes since then though including some relating to the new vector code and the settings, but the last binary is not "old" (It's from the 11th October). I will update the binary though.

Thank you @BuZz if there are still problems with vectors in mame2003 after this binary update I will work to resolve them.

@BadMojo12 ok understood. Advmame can be installed as an optional package. I think it used to be installed by default but now its one of the optional packages. You'll need to become familiar with the Retropie directories. Can you get your pi on your network and drill into it from your pc with ftp or ssh? I use ftp to copy roms and move files around, and ssh to edit .rc files. I will also use a keyboard on the pi to run tests. Just about everything I've learned came from these here forums and the documentation.

@nilsholgersson pcsx-rearmed is known to have a lot of compatibility issues, being fast enough on arm processor came at a cost... and don't expect fixes for this, notaz (the main developper) has been quite inactive for years.
Your best bet is to use either the original hardware or a more accurate emulator (i would recommend beetle-psx-libretro) on a hardware more powerfull than the pi (i would say something with a cpu as close as possible to 3Ghz)

Have at it. I stole the heart of it from Heath Ledger's Joker.

@calom Exactly ^^
