Megatouch XL CD-ROM to Hard Drive
obcd:
Right, the results with fakecd look good.
Download the fakecd zip. It should at least contain fakecd..exe and infocd.exe
I mounted your iso with virtual clonedrive (The original disk in a drive should work as well)
I opened a command prompt.
Next, I ran infocd d:\mega e:
d:\mega is a folder on my harddisk
e is the drive letter containing the cd (virtual clonedrive drive letter in my case)
It should create a fakecd.dat file in the folder you specified.
delete the contents of the mega folder on the compact flash card.
copy the fakecd.dat file to the mega folder on the compact flash card
copy the mega cd files and folders to that mega folder as well.
The reason I delete and copy them again is because I am afraid that previous tests might have altered something to the files that could trigger the shock error.
copy the fakecd.exe file to the c:\fdos\bin folder.
edit the c:\autoexec.bat file
find the following lines:
SET PATH=%PATH%;%DOSDIR%\DOG;%DOSDIR%\MERIT
swsubst f c:\mega
and change to:
SET PATH=%PATH%;%DOSDIR%\DOG;%DOSDIR%\MERIT
lh c:\fdos\bin\fakecd c:\mega /L:F
The last lines of the autoexec.bat are:
rem --- Start up the XL program
call c:\launchit
:donemega
So, I copied the c:\mega\launchit.bat to c:\launchit.bat
And I tweaked it a little:
:runit
d:
f:\delall
copy f:\exec\megacdll.exe d:\
copy f:\thefiles.dat d:\
megacdll
pause
echo if not exist d:\escape f:\reboot.exe
This gives the opportunity to read possible errors.
In my case it says
Invalid Key !!!
Normally, yours should behave different.
I hope I didn't forgot a step.
Good luck..

OK well I got a bunch further and guess what? Now I get an "Invalid key" error.
I completely pulled out the Dallas chip and put it back in. I also tried cleaning the "battery" key thing and making sure it was seated properly. Still "Invalid Key" error. I have no idea how this thing worked absolutely fine last year and now the DOS ROM chip dies and the Dallas key dies, but I am pretty much going to toss this thing in the trash sometime next week. You gotta love when anti-piracy measures lock out legitimate owners!
Thank you anyway everybody's help even though it didn't end up working in the end. :( I really, really wanted this thing to be part of my home.

invalid key error
even though it is annoying
could be as easy as crap in your cf card that never got cleaned off
and or a hiccup in your iso

I already was afraid of this.
You likely have a problem with your unit io card. Basically, that card combines a number of things.
1. The boot flash drive. (Which you have disabled at the moment)
2. The nvram which is memory mapped in segment C800 (If I remember correctly) (For the highscores)
3. A soundcard with buildin amplifier
4. An interface to the security dongle.
5. An interface to the coin acceptor and the test and service button. (Should be able to drive a mechanical counter as well)
6. An interface to the 16 dipswitches on the board
7. An interface to additional in and outputs that can be used to connect buttons (currently unused)
8. A serial interface that can be used to connect a pc
If you have a problem on your io board, it can affect one or more than one of it's functions.
In your case, the boot flash drive is failing, and probably the interface to the security dongle as well.
It wouldn't suprise me that none of the other functions are working either.
I have one lying in front of me with similar symptoms.
A common problem are the pcb finger contacts or the riser card finger contacts. You cleaned those already, so you are facing other issues.
I have a couple of test programs to read and write the nvram. They can be used to test it's functionallity.
You could try to find a second hand io board on Ebay if you are willing to go on with the unit.
If you are not, I am interested in buying the security dongle and it's small interface pcb (the board that connects to the 5 pin on the io board).

OK thank you. Unfortunately nobody on eBay is selling an i/o board. Just the motherboard which I don't need :(
Should I just suck it up and buy something like this? Seems ridiculously expensive: http://www.ebay.com/itm/Megatouch-XL-to-Maxx-Ruby-2-Upgrade-Update-Kit-5000-6000-Gold-Platinum-etc-/361121547775?hash=item54148585ff:m:m2_55DvZeZXmuziQoTOz4xw
