Some improvements
Polishing work on the Run'n Gun core continued this week. The core looks now much better on MiSTer and SiDi128 but the Pocket version still needs a few more days of work.A while ago, one of our directors requested a core for Caliber 50, a game similar to Ikari Warriors. This title shares some logic with the JTKIWI ...

Service Release
These past two weeks we stopped working on new developments to go back to reported issues in released cores.

That was the cas...
Golfing Greats/OutRun back on Analogue Pocket

Laser Ghost
In 1990, after Ghostbusters II release in 1989, SEGA released their first light gun arcade shooter: Laser Ghost (if you are thinking of The House of the Dead, that would still take six more years to come alive!).
