AtariBlast! was completed in Sept 2016 - and can be downloaded from the Atariage website - in 5200 and Atari 8-bit versions.
The former runs off the Atarimax Ultimate 5200 SD cart - the later in 2 versions - one for 8mbit flashcart (eg. Atarimax) - which will run on 16K machines - eg. Atari 400 - it works fine because I tested it out. and another version for Atari 8-bit computers upgraded to 1088K. You have to register with Atariage - to download the files.
They also at the Atarimax website in the forums section. Same condition applies I guess...
Earlier this month - work was completed for the Scramble conversion for Atari 5200 and 8-bit computers.
Download for the computer version is found here -
http://atariage.com/forums/topic/281589 ... ion/page-1It's 1/2 down the page for the official version - one at the top of page - is the hacked 5200 version.
Videos have been posted on Youtube and can be found easily there.
This is not a straight conversion of 'Scramble' as other conversions have been. There are some enhancements done to the graphics - with added animations present. It does feature various 'easter eggs' in the game - if you get to the advanced difficulty levels. Any keen arcade games player of the coin-op should be able to get to these - without too much trouble?
The Atari computer version - does support the MegaDrive gamepad - so that two fire buttons will work. The gameplay remains the same as the coin-op game.
A version for PAL in mind will be released some time in the future...
This should end up in the official cart version - that will be available from Atariage - in the next month or so...
The 32K cart will need 32K of RAM minimum to run. Meaning - it will not run on 16K Atari computers.
