ROM Hacks

I have started looking at dissecting ROMs to add features that are needed like free play or other functionality.  Email if you have a request, and I'll look at doing the mod.  These are offered here TOTALLY FREE, but for those who wish to donate, its greatly appreciated.  These hacks can take quite a bit of time and effort!  If you need these burned to EPROMs for you, visit Hobby Roms (Link below). They are very reasonable, and fast on shipping!

 

ASTROBLASTER FREE PLAY v2 This hack gives previously unimplemented free play mode to Sega's 1981 Arcade game. It was designed to keep the attract mode in operation so that you are not constantly faced with the blue credit screen. These ROMs will only work with the Version 2 ROMset (ROMs on EPROM Board in range of 888 to 906). DIPSW 1, 1 turns on and off freeplay.
ASTROBLASTER FREE PLAY v3 This hack gives previously unimplemented free play mode to Sega's 1981 Arcade game. It was designed to keep the attract mode in operation so that you are not constantly faced with the blue credit screen. These ROMs will only work with the Version 3 ROMset (ROMs on EPROM Board in range of 907 to 925). DIPSW 1, 1 turns on and off freeplay.
ROBOTRON PAUSE solid blue label ver 1 This hack gives previously unimplemented pause mode for Williams Robotron Arcade game. It was designed to allow pausing during game play using the "1 player start" button. These ROMs will only work with the solid blue label version. This version allows the movement of the player during the pause. Its kinda surreal, so I will keep it posted here :)
ROBOTRON PAUSE solid blue label ver 3 This hack gives previously unimplemented pause mode for Williams Robotron Arcade game. It was designed to allow pausing during game play using the "1 player start" button. These ROMs will only work with the solid blue label version. This version fixes the issue of movement of the player during the pause. This is a true pause. It also provides on-screen status of the paused game.
JOUST PAUSE white/green label ver 2 This hack gives previously unimplemented pause mode for Williams Robotron Arcade game. It was designed to allow pausing during game play using the "1 player start" button. These ROMs will only work with the white/green label version. This version fixes the issue of execution corruption during the game. It also provides on-screen status of the paused game. If you have ver1, delete it - it does not work past the 3rd stage! Also, to use ver2, you must have the original ROM12 installed.  If you get a ROM error, make sure you have done this! (ONLY if you burned the ver 1 ROMS)

The Readme file has interesting notes for this set - for the programmer's interest.
