No. Not only was AGA significantly different at the hardware level, but it had limitations which adversely affected compatibility and required an updated AmigaOS with major changes. The limitations of AGA could be largely done away with today using newer hardware. An FPGA AGA implementation can be more compatible than the original AGA hardware and much faster. The FPGA CPU can also be more compatible and faster using writethru caches than the 68040 and 68060 Motorola CPU caches which caused incompatibility with self modifying code. Of course we can change the FPGA configuration for multiple hardware simulations but it is still impossible to have one setup which works with all games. WHDLoad is still needed to use the most games possible.
