I notice you don't have this game (released July 2011) in your great database. Please feel free to share if you wish
From http://www.sheddyshack.co.uk (site no longer exists):
I’m very pleased to be able to finally announce the release of Space Harrier for the Atari XL/XE series of computers with 64K of memory or more.
Due to the size of the game it is only available as a cartridge image which can be run on emulators such as Altirra, or run on a real machine with an 8mbit Atarimax Maxflash cartridge and programming image
Notes:
Reduce screen flicker on real TV or monitor by adjusting brightness and contrast
Reduce screen flicker with emulator by choosing “Blending” or adjust monitor refresh rate to same screen rate as emulated Atari (NTSC= 60Hz, PAL=50Hz)
Thanks for the database entry. Here are some alternative screenshots taken with blend option on Altirra which works much better for in-game screenshots.
Now includes fix for “Bank 0″ Maxflash cartridges
Small optimize bug fix (30th August 2011)
[Edit] Sorry for double post. I also replied with this to an old "New Releases/Homebrews" post, but "MIA" seems the better place now
