Tough game, even with a joystick. I asked about cheats. I’m going to try them.
I never did get theses cheats to actually work. I tried 3 different versions of Sea Dragon (different cracks) and none restarted the game from the monitor * prompt. I’m attaching the 3 version startup screens…note cracker names.
The control-J does get you 9999 units of air instead of the default 6000.
Here I’m running the AppleWin Emulator in Windows with Parallels on my MacBook Pro.
I bought the GS8RAMROM from http://www.a2heaven.com. It comes with ProDOS 2.4.1 in ROM and boots incredibly fast to it. The whole thing is new technology that runs with very little power drain and really fast ram chip. Because it has a battery backup (CR2032) for the 8 meg ram I thought it would back up what was in RAM or on the RAM disk when the computer was powered down. —- My goal was to create a bootable GSOS 6.0.1 ROM/RAM disk. However, the creator has not written the firmware yet to accomplish this. He says he is about 70% done. [ Note: as of Dec 21, 2017 there is no firmware upgrade; so use as a Solid State Ram Drive ]
Also, the IIGS Rom3 unit has a bug in it that does not allow you to boot from RAM. When the author writes the firmware he will create the work around to correct this situation. I had been running my RamKeeper from Applied Engineering with a 6 meg GSRamPlus card to allow me to boot GSOS from Rom Disk. It works very well but I have no battery backup for it.
