I'm glad someone found objn64 useful :) looking back it could've been optimized better but it was Good Enough when I wrote it. I think someone added png texture support at some point. I was going to add CI8 conversion, but never got around to it. On the subject of XBUS vs FIFO, I trialled both in a demo I wrote with a variety of loads. Benchmarking revealed that over 3 minutes each method was under a second long or shorter. So in time messing with them I never found XBUS to help with contention. I'm sure in some specific application it might be a bit better than FIFO.
By the way, I used a 64k FIFO size, which is huge. I don't know if that gave me better results. |

I'm just a nobody who wrote DotN64, and contributed a lil' bit to CEN64, PeterLemon's tests, etc.
For objn64, I don't think PNG was patched in. I only fixed a handful of things like a buffer overflow corrupting output by increasing the tmp_verts line buffer (so you can maximise the scale), making BMP header fields 4 bytes as `long` is platform-defined, bumping limits, etc. Didn't bother submitting patches since I thought nobody used it anymore, but I can still do it if anyone even cares.
Since I didn't have a flashcart to test with for the longest time, I couldn't really profile, but the current microcode setup seems to be more than fine.
Purely out of curiosity, as I now own a SC64, is the 64drive abandonware ? I tried reaching out via email a couple times since my 2018 order (receipt #1532132539), and I still don't know if it's even in the backlog or whether I could update the shipping address. You're also on Discord servers but I didn't want to be pushy.
I don't even mind if it never comes, I'd just like some closure. :p
Thanks again !
