Progress May I - Sprites & (french) talk (Patreon)

Last week-end, I attended a french arcade event organized by HFS (https://www.hfsplay.fr/). I met great, passionate people, played very Japanese games, ate sandwiches, saw a bunch of CPS2's and... gave a short talk about this project in front of ~30 people.

I reached my only goal: I didn't faint !

Apart from that, it was very motivating to show the project "live", instead of posts here or on Twitter. Especially later on, when people were curious and asked for details :)
It was recorded on video along with more interesting stuff (tournaments). If you want to hear my nerd voice, it's over here: https://www.twitch.tv/hfsplay/videos/all

The slides don't show anything new, but I did start piecing together infos and chronograms regarding sprites when I got back home.
I'm not sure I'll be able to run full tests with my DE-1 board as I did with the fix layer. I'll probably have to get the verification board done before that can happen.

This post's picture shows how horizontal sprite shrink makes the rendering cycle skip pixels (12 pixels written, 4 skipped). A custom program was written and burned to an EPROM to replace an AES cart P1, allowing to test how sprites are rendered in "controlled conditions".

Anyways, more pieces added to the puzzle...
