Copperline 1.0.0 is out, the first stable release of my cycle-driven #Amiga emulator. OCS, ECS and AGA, A1000 to A4000, CDTV and CD32, 23 releases since the source went public in June. www.patreon.com/Copperline/p... 🧵 1/5

For developers: a debugger beside the running Amiga with reverse stepping, a bus-cycle frame analyzer, GDB, VS Code source debugging, profiling, an MCP server, and now WinUAE-style debug output ports. 🧵 4/5

Netplay peers all need 1.0.0, RetroArch states need recreating, and macOS 14.2 or newer is required for Mac users. Thanks to everyone who tested the release candidate. Details: www.patreon.com/Copperline/p... 🧵 5/5

patreon.comCopperline 1.0 | CopperlineCopperline 1.0.0 is out. It is the first stable release, two weeks after the release candidate and the 23rd release since I made the source

It boots with the bundled AROS ROM, runs WHDLoad games directly, and has save states, rewind, run-ahead, CRT shaders and rollback netplay for up to four players. It runs on macOS, Windows and Linux, in a browser and in RetroArch. 🧵 2/5

New since the release candidate: Smart framing brings off-centre pictures like the CD32 boot logo into view, native 1:1 screenshots, VHD hard disks, window and monitor options, and an AGA sprite fix for Castlevania AGA. 🧵 3/5

Copperline 1.0.0-rc.1 is out! The first release candidate for 1.0 of the #Amiga emulator. Please try your usual games and demos, and report anything that worked in 0.21 but not now. www.patreon.com/Copperline/p... 🧵 1/5

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

If testing turns up nothing serious, 1.0.0 is next. Netplay peers all need rc.1; RetroArch save states need recreating. www.patreon.com/Copperline/p... 🧵 5/5

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

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

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...

Two computers, two mice, one game of #Amiga Lemmings. Copperline 0.20.0 is out, with Netplay for two-player Amiga games over the Internet. I’ve put a video and the release details here: www.patreon.com/Copperline/p... 🧵 1/5

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

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

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

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

Which bezel is better for Copperline? #Amiga

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

Bluesky of course compressed it to hell, it looks much better in real life.

Version 0.10.0 of Copperline is out, a massive 256 commits between 0.9.0 and 0.10.0! I do not recommend anyone but developers use this release yet. A lot of the chipset code has been re-written and it has introduced regressions. Bug fixing will be the next beta focus. #Amiga
