Yes you will have the problem with all double disk games and the toruble boils down to 1 of 3 reasons.

1, You have a Stealth chip installed incorrectly or,

2, The hex code on your Stealth chip is duff and doesnt give you time to swap to the second disk before it shuts down, or

3, You may be taking to long to change the disk and the chip is shutting down before you have closed the lid.

Standard Stealth chips should give you 5 seconds to swap to the second disk so if you take longer then they shutdown and then the second disk isn't recognised, there was also a problem with some of the original Stealth code where the 5 second time out didnt actually work at all!

my guess would be either option 2 ot 3 and if it proves to be option 2 and you are handy with a soldering iron, then please contact me and I should be able to help you out.
