Enhanced synchronization between the RP2040 and the computer's address and data bus, supporting both 8MHz and 16MHz operations.
Automatic switch to 8MHz, cache-disabled mode during "hybrid mode" operations involving volatile data in ROM4 and ROM3 ranges. The firmware now detects a MegaSTE system and adjusts read/write operations to ROM3 and ROM4 accordingly, ensuring reliability.
