- The hello-ipl3font example will initialize the IS Viewer 64 as an I/O backend if detected. - Run the example with `cen64 -is-viewer` to see the console output.

This needs to be fixed to be compatible with real IS-Viewer 64 hardware. I have attempted to correct the emulation in Cen64 over here: n64dev/cen64#232 and if that PR is accepted, I'll push an already-working commit here to fix it! <3 |
- This implements the real IS-Viewer 64 protocol, not the "HomebrewStdout" protocol.

This doesn't actually work on hardware. From very minimal testing, reading and writing ROM addresses through memory-mapped I/O has some unexpected behavior. The CPU seems to read back its own writes, even though the physical memory is read-only. More testing is needed, but I will probably switch the IS64 detection to use DMA to avoid the readback issue. |
