And for game number 10,
I present a new crack from an original Mindscape diskette in my collection. The available cracks from the web had a sound bug that was out of control. I had to create a new file from original to solve this issue. My original C64, 1541 and SuperSnapshot cart did the trick.

David your website Joystick page looks great, I guess at some point I can add a page to my site for the games I convert and you can link if your not sure about hosting the game files. I know it's a big 'Can o Worms' when it comes to the games and (C) etc. I just want to convert 13 disk images worth of games for my hummer, and share what I do convert. I guess I will also convert some extras as the flash is able to take so many write cycles I will be sure to change the games in ROM after a while.
I also have Contra ready for a test on the Hummer at lunch.
Also the idea with Abyss seems to be to collect as much of the blue potion bottles as possible. You can also press the button when you are on the yellow machine device and it will expel a diamond like object. If you push that object into one of the spiral pattern pits you will get a large increase in % completed. If you press the button on a wrench then you will pick it up. Then when you jump onto a platform with a square in the center you can take the square with you when you jump off by hitting fire. Then you can jump onto a square with a hole and press fire to place the square in the platform. In this way you can really complete the puzzles. It's not easy at all with the relentless beasties.
There are some switches that will change the layout of some tiles and create a way to go to some areas also. For me a lot of the fun was figuring out how to even play this crazy game. The music kept me at it while I figured some stuff out. I still have not been able to figure out how to save a game. It has the restore game feature so there must be a way. that would really help this game out a lot.
There is a helicopter type sprite in the game that will take you to the next level.

Okay.. I finally caught up with you on the website. However, I haven't even had a chance to try the last two yet. I've been having an affair from my DTV... I've been hacking a ZipIt Messenger the last two days instead of DTV hacking. I'm sure I'll come back to my DTV eventually, though.

I have been wanting to play this on my hummer now for so long I guess I had to do the conversion at some point. I now present to the Hummer DTV hackers, perhaps the best shoot'em up ever to be played on the C=64, Commando!

Pacman / Ms.Pacman Pitfall/Pitfall II Xevious Araknoid Jumpman Jr. Impossible Mission M.U.L.E. Spy vs. Spy International Karate
Well I guess I can knock a few of these out. I took a stab at Ms. Pacman but was having some king of issue with it . Arkanoid, Krackout & Jumpman Jr. should be done soon as I like them a lot. I came quite close to completing Pitfall II on my Atari 2600 so you might find that here soon as well.
I have recently created a user-port adapter for my real C=64 and that has really helped a lot as now I can test in real time. This is a lot faster than swapping back and forth from VICE to the Hummer via 1541.
Since I am crunching each file with Exomizer I may be able to get a huge collection into my hummer. I still have yet to flash the last ten games but I have tested them quite a bit. ;D
Also if 'Atomino!' is one you like then I should take a whack at it just for your help with the project!

Your wish is my command .
Pitfall for the C64-Hummer
In all this game required 5 bytes to be changed. I hacked it with a hex file editor on my pc before hand and tested it right on the hummer. It locked right up for my effort. I then tested it on my C64 UJS platform and it was working.... I scratched on my head until it felt like there was something there. I recall the DTV80 boot strap from the DPG document I had reviewed. I changed the file with the hex editor again to include the DTV80 in place of the CBM80. Bam it starts right up. Now maybe I can get a few more carts to work.

Thank you for pitfall. But I'm not sure I understand the DTV80 thing. I mean, I understand about the CBM80 string using on cartridge images. I did some experimentation on my real C64 years ago with burning EPROMs with my own software installed, so I had to learn all about that. But as the DTV doesn't have a cartridge slot, and this is something you would be loading from disk, I'm not sure I understand what the DTV80 does.

A good question. As it turns out the C=64 can actually run cartridges from RAM. The way it works is to load the file into the ram where the cartridge ROM would map to. for an 8K cart that maps to $8000-$9FFF this is no problem as it loads into free RAM for basic. Some cartridge files also map to locations that would be C=64 System ROM's. For these types of cart image files a boot strap must be used in ML to bank out the system ROM and jump to the ram below.
Since Pitfall is an 8K Cartridge that is mapped from $8000-$9FFF all that has to be done is load the file into ram @ $8000 and call SYS 64738. This will reset the machine and bootstrap from $8000 if it finds the CBM80 code in ram. Since the Pitfall file loads into basic ram at $0801 it seems clear that a short BASIC and ML stub is used to copy the memory from the $0800 range to the $8000 range, then call SYS64738. The boot strap at $8000 is detected by the kernal and control is transfered to the code specified at the $8000 vector.
However with the original file and the CBM80 code the DTV would just lock up after the relocation of the code. I was a bit puzzled by this as this is the problem I also had with Ms. Pacman. I didnt want this to be a problem since many of the games you requested are in fact cartridge images stored on disk. I cant be sure but I think the info about DTV80 is in the Kernal Document, I changed CBM80 to DTV80 and gave 64738 a try and as you know it now works.
Pitfall II is converted 95% but I cant get the keyboard scan code to read the F1 key. Should be able to get that tonight.
