a7800DS
--------------------------------------------------------------------------------
a7800DS is an Atari ProSystem 7800 console emulator.
To use this emulator, you must use compatibles rom with a78/bin format.
Do not ask me about such files, I don't have them. A search with Google will certainly
help you.
Features :
----------
Most things you should expect from an emulator.

History :
--------------------------------------------------------------------------------
V1.5 : 15-Dec-2020 by wavemotion-dave
* Overhaul of scaling and X/Y offsets so that more games look pixel perfect.
* More homebrews run... compatibility table added to the back end of this doc.
* More robust handling of High Score Cart and saving of files.
V1.4 : 13-Dec-2020 by wavemotion-dave
* Implemented Hiscore Saving per the HSC cart. Put the 4k highscore.rom (don't ask)
where your ROMs live. If found, it will enable saving of high scores
on all 9 original games (Asteroids, Joust, Centipede, Xevious, Dig Dug, Galaga,
Food Fight, Ms Pac-Man and Robotron) as well as most of the newer homebrews.
V1.3 : 12-Dec-2020 by wavemotion-dave
* Backported some fixes and emulation timing improvments from Prosystem 1.3g
plus the Wii version. Renders a few more games playable.
* Fixed region for Froggie and Beef Drop - they now look right and play
at full speed.
* Minor other improvements as time permitted.
V1.2 : 10-Dec-2020 by wavemotion-dave
* More speed improvements. Fixed some 320 pixel games. Improved sound.
V1.1 : 09-Dec-2020 by wavemotion-dave
* Brought back to life... cleanup and about a 50% speed improvement, better
screen rendering/scaling and slightly improved UI features.
V1.0 : 24/05/2011
* Initial release based on my a320 version (which is based on Prosystem 1.0.3)
* Compiled with last version of Devkitpro/libnds, so DSi compatible \o/

How tu use a7800DS :
--------------------------------------------------------------------------------
YOU NEED PERHAPS TO PATCH THE NDS FILE WITH THE DLDI PATCH BEFORE USING IT.
Unzip a7800DS.nds from the a7800DS.zip archive in a directory of your flash / (micro) SD
/ MMC card.
Put the a78/bin files where you want on your flashcard.
That's all, a7800DS can be use now :) !
When the emulator starts, click on the cartridge slot to choose a file. you are use Up/Down
to select a file, then use A to load it.
Controls :
* Direction pad : the joystick ...
* A : Fire button 1
* B : Fire button 2
* SELECT : SELECT Button
* START : PAUSE Button
* X : FPS Display
* Y : Full-Speed
* L/R : Shift screen up/down by 1 pixel
Use stylus on buttons for other actions on bottom screen.
High Score Saving works if you have highscore.rom (exact name and case) in your
roms directory where you load your games... also, you MUST press the HSC button
if you want to snap the Saved Scores out to the flash card. It's not something
I want to do as the game runs... so you must do it... the high scores will also
auto-save if you quit the emulator or select a new game.
