The bundled AROS ROM is refreshed: no more sheared hires screens. The manual was checked against the program, which also fixed some debugger register decodes. High-density floppy images are now refused instead of crashing the guest. 🧵 4/5

The debugger can now watch device registers such as Akiko's and the CIAs', logging each CPU access with its value, PC and beam position. A new trace times every command the CD32 sends its drive, from issue to last sector. 🧵 3/5

Desktop netplay now seats up to four players. Players 3 and 4 use the parallel-port four-player adapter, as they would around one Amiga. The host relays everyone's input, so only the host needs to be reachable. 🧵 2/5

To be fair, 5 minutes with an AI can probably write those tools. If that is all vendors are giving, they won’t survive long.

For normal video recording it is ALT+R in Copperline Windows. The previous 10 seconds as a GIF is ALT+SHIFT+G. It can also be scripted to take video and screenshots.

Copperline 0.20 now has a shortcut which converts the previous 10 seconds of gameplay into a GIF. So, of course I tried it with an early developer build of @brazengameplay.bsky.social's UrbX Warriors. Still 4 days left if you want to back UrbX: www.kickstarter.com/projects/ton...

Save states now have thumbnails, so you can see where you left off. You can also save a GIF of the last few seconds of a game or demo. Paula audio has had some attention too, with less aliasing. More details at www.patreon.com/Copperline/p... 🧵 5/5

There’s a new libretro core for RetroArch too. It runs A500, A1200 and CD32 software, including WHDLoad packages, and supports RetroArch’s own Netplay. 🧵 4/5

I’ve also rebuilt the debugging workspace. The Amiga screen sits beside the CPU debugger, Frame Analyzer and Console. You can inspect a frame, edit memory and see what the machine is doing, all in the same window. 🧵 3/5

The host shares the machine setup and game files. Floppy changes stay in sync too, so there’s no need for both players to find the next disk. You can play desktop to desktop, or browser to browser. 🧵 2/5

My friends Stoo Cambridge and @tonywarriner.bsky.social created @brazengameplay.bsky.social, they are developing a new Amiga. It is only fitting that I run a dev build of it on the A4000 I restored that Stoo used to own in the 90s. Back it on Kickstarter! www.kickstarter.com/projects/ton...

Copperline’s web version is currently broken. A bad version accidentally got deployed and then GitHub broke, so I can’t deploy the fix. On a positive note, visual improvements are queued up for it. I apologise for the inconvenience.

It may have been overkill, but I took the datasheet of the Philips tube used in the Commodore 1084 monitor and used it to recalculate the angles of the CRT shader in Copperline. This is almost ready to be included in the next release. #Amiga
