I don't have a real XT machine to test this, but remember played those games with Hercules about 35 years ago. So I tried PCem V17 and noticed that SIMCGA …

Some PC-booter games are supported by simcga v4.0, e.g. WinterGames and World Karate Championship On a real machine with hercules card, we can use "simcga s" to play them. If you can dump them to diskimages, modify them to bypass keydisk protection, those games also work under DOSBox. However, we …

There appears to be a bug in MKBOOT.EXE where an invalid drive number is used for INT 13h/Ah=00h (reset), which returns an error and is retried in an endless loop. The bug can be fixed by modifying the bytes at offset 15E4 from CD 13 72 0F 33 D2 to 33 D2 CD 13 72 0D. After modification it will at …

Calm down! If anyone is interested send me a PM, and I send the software by e-mail. The files are, just, a few kilobytes in size. PD: MagicKey 3 is already uploaded on archive.org. Just type "MagicKey" on the search box. I'll try to upload there the collection of different versions of SIMCGA, MONO …

Dominus, Firefox says that your link is not safe. Then I go to sourceforge.net/projects/vdos/ and look it's description. It seems that vDos is not meant for me. I have a game about asterism/fate in Chinese Language, it runs under Hercules mode only and needs a printer for some result. It works fine …

This game seems use similar keydisk copy protection method as Rampage, I guess. You can try to use WinImage to make a blank 360K diskimage, e.g. disk.img. Then copy all files of this game into it. Run this game like following : imgmount a disk.img -t floppy a: Then run the main executable file. Good …

I don't know anything about your Hercules card. But your problem seems caused by the OS you used (and/or timer on your motherboard). Anyway, as I said, just try "PCE" or the lastest "DOSBox_SVN".

Wow, it does start with the simcga you posted! It doesn't "work" though, as with HGCIBM there are so many problems that it's unplayable It works/playable here. Do you use DOSBox ? In fact, this game is keydisk copy protected. You can only use Teledisk to dump diskimages and run it using PCE without …
