![]() It appears the base board could have been the same even though the control register differs. We could really use some high quality pictures of this hardware so some comparison to the MK3 board can be made. The ROM size was doubled from 16 kbyte to 32 kbyte with this update. MK4 extended the hardware even further so it now allowed banking. To add to the mess Datel also sold MK3 carts on which the Fastload was named Diskmate. It appears the same hardware was used for selling the DISK MATE on which the button was replaced by a switch as the Disk Mate software did not support bank switching. It appears the continous usage of even tiny menus on the earlier available Final Cartridge I and II encouraged the developers to add such things as well. MK3 introduced a hardware change and the ROM was largely rewritten. The MK1 and MK2 ROM dumps are not carrying version numbers so there is some guessing involved which explains our labeling of the binaries in the archive with MK2 v1 and MK2 v2. The base for the MK1 freezer obviously has been the Snapshot 64 ROM which underwent only minor changes on the freezer part. MK1 and MK2 likely (we cannot confirm this yet) share the same hardware base and are direct branches of the Snapshot 64! The Action Replay cartridge series developed by Datel was released in the middle of 1986 and got several updates during the years. ![]() See Tech Section and Extension Programming Check Action Replay Category for even more! ![]()
