| | | | | | | | | | | | | | | | | working (#12617) * This adds basic execution to XA core. It emulates enough of the XA to give fearless and superkds working sound. * only the exact forms of the opcodes used so far have been implemented * no optimizations have been done, use of const, inline use, templates etc. are planned for a future update; code is still primed for debugging and development * overall structure, code style are not 100% final (see above) and will be adjusted as the CPU is better understood * peripherals, interrupts etc. are not yet fully implemented, nor is anything outside of the page zero mode used here due to lack of test cases Machines Promoted to WORKING ---------------------------------- Super Kids (S019CN) [David Haywood, XingXing] Fearless Pinocchio (V101US) [David Haywood, XingXing, Peter Wilhelmsen, rtw] --------- Co-authored-by: David Haywood <hazemamewip@hotmail.com>
* cpu/xa: New Philips XA disassembler (#12504) mamehaze2024-06-291-0/+1904
* show size types on these for consistency with IDA output (manual indicates they're usually optional, but does show this syntax in places) * use the real CPU type (with internal map for internal ROM space) rather than 'XA' directly. --------- Co-authored-by: David Haywood <hazemamewip@hotmail.com>
