Sound "Klax wave" have lower volume.
The title screen with the amazing music is missing.
It is not possible to choose easy, medium, hard.
Game play i could find no difference. (tested only 20 minutes...)
You can add additional 16 pcs 1Mx1 chips (120ns or faster). But you have to deactivate the 512Kb on Board.
Connect RAS0 and CAS0x lines at Memory chip side of the internal 512Kb to +5V. Or remove the internal 512Kb.
Check if RAS0 and CAS0x from MMU side is connected to the unpopulated sockets.
Maximum memory for 520ST is 4MB. (without additional logic)
6 sockets -> TOS ROM, not RAM!
16 memory chips -> 512Kb Memory, total RAM including Videoram
32 memory chips -> 1MB Memory, total RAM including Videoram
520STF(M) and 1040STF(M) is the same board, the difference is only the memory assembled.
@GadgetUK: please update your FlashCard with Firmware x.40, i added auto size mode and some other changes in the menu.
In any case of questions please send me PM or email, because this thread is about jungle jack...
But if the comm app use the wrong settings it will not work.
Please check the settings with a terminal after upload with the comm app.
Please note: the change of the settings will only have an effect for the next upload.
As already found, the header data is not correct. If my FlashCard is used with the latest Firmware (x.40) and the function "auto size" is used the game will not start.
If you want to use "junglejackbeta1" with my FlashCard please switch off "auto size" and use the following setting: "256K/BLL" and "LNX"
Or use a hex editor and change address $0007 from $04 to $00
Background: my FlashCard support 2nd bank and if the information for 2nd bank is found the setting of the memory interface may cause problems if 2nd bank is not used.
@LX.NET: please set byte $07 of the header to $00 for the next beta to avoid trouble with my FlashCard.
Ich habe 85 für ein A2600 mit einem Joystick (kannten wir damals schon nur unter dem Namen) für 179 DM gekauft. Und dann noch ein paar Kassetten für 19/29DM. Donkey Kong, Pitfall!, Enduro.
Die Scans sind Super, die Kataloge habe ich immer gerne angeschaut. :-)
Yes, additional address decoding is required.
