I discovered "Atari800WinPlus4.0" and it plays all the Atari 5200 games (except Pitfall, Wizard of Wor, Star Trek) ..... it also plays the Atari 800XL games and interfaces with my TV in fullscreen excellently.
I still need to see if I can get those three games working though. They do come up and look great .... I just can not "start" the game....oh well.
Thing is ..... I could not figure out what the command line parameters were for this emulator. It originally seemed like a windows only GUI application, however, I looked at the source code and found the following command line options were available:
-configure Update Configuration File"
-config <file> Specify Alternate Configuration File"
-atari Emulate Atari 800"
-xl Emulate Atari 800XL"
-xe Emulate Atari 130XE"
-320xe Emulate Atari 320XE (COMPY SHOP)"
-rambo Emulate Atari 320XE (RAMBO)"
-5200 Emulate Atari 5200 Games System"
-nobasic Turn off Atari BASIC ROM"
-basic Turn on Atari BASIC ROM"
-pal Enable PAL TV mode"
-ntsc Enable NTSC TV mode"
-osa_rom <file> Load OS A ROM from file"
-osb_rom <file> Load OS B ROM from file"
-xlxe_rom <file> Load XL/XE ROM from file"
-5200_rom <file> Load 5200 ROM from file"
-basic_rom <fil> Load BASIC ROM from file"
-cart <file> Install cartridge (raw or CART format)"
-run <file> Run Atari executable file (COM, EXE, XEX)"
-state <file> Load saved-state file"
-refresh <rate> Specify screen refresh rate"
-nopatch Don't patch SIO routine in OS"
-nopatchall Don't patch OS at all, H: device won't work"
-a Use OS A"
-b Use OS B"
-c Enable RAM between 0xc000 and 0xcfff in Atari 800"
-v Show version/release number"
Anyway, I use the following command line parameters to launch games:
ATARI5200: atari800win -5200 -ntsc -cart "D:\myGamePath\game.CAR"
ATARI800XL: atari800win -xl -ntsc -run "D:\myGamePath\game.exe"
IMPORTANT NOTE: Originally my Atari 5200 game roms had an extension of "bin" (or "a52"). What you need to do is start each game in the Atari800Win emulator manually by going into the "File\Attach Cartridge" menu and selecting the bin (or a52) game file. If the game is not considered a "true" cartridge file (ie: does not have specific cartridge header information included) then the emulator will ask you to select whether the game is a "One chip 16KB 5200 cartridge" or "Two chip 16KB 5200 cartridge". You can try either and see which one works. Once you find which one works you can go into the "Misc\Convert" menu and select "ROM to CART" option. This will allow you to convert a BIN (or a52) file to a cartridge (CAR) file by appending the correct header cartridge information to your file. Dont worry, it will not overwrite your existing ROM file but will instead ask you to save it to a different file ..... just save it as extension CAR. Once the file has been converted you can try to "attach" the cartridge (CAR) file via the menu and will now see that the emulator starts the game automatically.
Converting does not take long since the Atari5200 only has about 90+ games...... and the actual conversion is super quick.....
Anyway, thought I would inform everyone that a good Atari5200 emulator does exist...... enjoy!
