Jum52

15 September 2002
This is an Atari 5200 emulator for PS2.
The 6502 CPU emulator source is heavily based on a distribution
by Neil Bradley. The POKEY sound emulator is a modified version
of Ron Fries POKEY emulator.
The rest is by me, using Bigboy's PS2 framework
v0.8 Changes:
1. Incorporated Jum52 v0.8a updates
- better collision detection
- more accurate ANTIC cycle counting
- some games broken, but more fixed
2. Converted PS2 code to use ps2sdk 1.1
3. Memcard handling for load/save state
4. Removed CD handling code.
5. Implemented player 2 controller
6. Modified to run off the MC
-
Most carts will run. These games give problems:
Decathlon
Mr. Do's Castle
Quest for Quintana Roo
Rescue on Fractalus

- Not supported yet!
Joystick:
From the Options Menu (press SELECT button), select whether to use the D-PAD or the Analog Stick for control, by toggling "Controller Mode" (press RIGHT on the D-PAD).
Robotron / Space Dungeon control mode can be activated while in Analog mode by selecting Robotron Mode On in the Options Menu. This allows you to use the left analog stick to move, and right analog stick to fire.
Pengo control mode is activated automatically if you load Pengo. You can also activate it from the Options Menu. Some other games may work better with this mode.
Many games do "auto-calibrating" while you play. Moving the joystick handle in a big circle while chanting "work dammit" usually gets it working OK. Some games also calibrate the centre position of the joystick at the start of the game or at the start of a level, so you may have to be careful to leave the joystick centred when pressing start.

You will need:
A PS2
The files in this package, along with some 16k or 32k Atari 5200 cartridge
images, cut correctly to CD.
NOTE: IF YOU DO NOT HAVE A WAY TO BOOT A CDR, THEN YOU CANNOT RUN Jum52 ON YOUR PS2 !!!
When creating and burning the CDR, remember:
1. Rename your roms to DOS 8.3 format
2. To edit FILES.TXT to match your roms and directories
3. Check your SYSTEM.CNF points to the correct .ELF
3. ISO Mode 2 CDROM-XA, Level 1 filenames
The format of the FILES.TXT file is the same as that in Sjeep's PSMS
emulator package, except that you must put the device specifier "cdrom0:" as a prefix in your ROM paths. See the included FILES.TXT as an example.
There are 3 versions of the JUM52 executable (NTSC, PAL and AUTO) included.
Rename the one you want to JUM52.ELF before burning.
