Laser Ghost
Added 2025-06-13 16:30:47 +0000 UTCIn 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!). This game takes heavy inspiration from Ghostbusters in the System 18 version, whereas the Master System version presents a different gameplay.
After a lot of work on the graphics layers in order to support simulation of saved states, we have been able to fix the graphics of this game. As it happens the change needed to the source code was rather trivial. Other System 18 games look almost ready for prime action too so expect them in the following weeks.
The game is playable using Sinden lightguns, mouse or joystick. It is a bit too easy for a mouse though, so if you are a mouse user you should rather turn the difficulty setting to the toughest setting.
Note that to pass the calibration screen you need to fire at the screen corners following the instructions, and then press the F2 key (equivalent to the board service/test) on a keyboard. We will remove the need for the keyboard in the next update.

2025-06-27 14:43:11 +0000 UTCGreat work! Does anyone know what the workaround is for all JTS18 System 18 games on Bang & Olufsen CRT TVs? I'm getting the out of sync wobbly lines on the TV. Would it be in Discord?

2025-06-19 11:38:27 +0000 UTCI think it should already work like that. We’ll check it.

2025-06-18 18:49:12 +0000 UTCYou can use older cores if they are on public release. The list of publicly available cores is available on GitHub. https://github.com/jotego/jtbin/wiki For example, Outrun core has been on public since 24-03-23.
