Recompiler: register jump-table targets with the cross-function
continuation pass before filtering local goto labels — BIOS jump
tables can legally branch into another discovered function's body,
so the prior local-only check dropped valid emit-side edges.
Dirty-RAM interpreter:
- Dispatch non-local JAL/JALR targets back through psx_dispatch_call
instead of forcing them into the interpreter when the target sits
in static-recompiled code (only targets in dirty pages stay local).
- New always-on flow + per-instruction ring buffers (insn_log,
flow_log) capturing reg state, current_tcb, and task fields for
post-hoc analysis. Block log gains t0/t1/t2.
- guard_yields counter; richer last_unsupported state (entry PC,
entry RA/SP, insn count) for dead-end diagnosis.
SIO: ACK is now visible across a small read window (2 STAT reads)
matching BIOS poll patterns that re-read STAT after CTRL_ACK clears
IRQ but expect ACK to still latch. Per-channel ack_irq_en captured
at shift start so a CTRL write that disables ACK_IRQ_EN mid-shift
doesn't suppress the firing. sio_init now zeros all paced-model
state. Read/write paths poll the debug server every ~1k accesses
so long pad/card spins don't starve diagnostics.
Memcard: auto-format slot files on first init when missing, so
the BIOS shell sees a present-but-empty card instead of "no card".
Runtime main: SDL nearest-neighbor texture scaling (no bilinear
blur on the integer-scaled framebuffer).
Debug server: large expansion of ring-buffer queries and dump
commands feeding the new insn/flow logs.
