Some good news. I’ve got a dedicated CRT monitor for my european Dreamcast, and I’ve also got a SD card reader for it. This should help a lot when I get around to developing for it again.
I should be able to easily dump screenshots, logs, config files and VMU data, as well as running a lot of Quake mods from the SD card for testing. Previously, disc space was a huge concern when testing, since it’s really hard to include a lot of mods on a CD-R and still get it to accommodate a lot of sessions on a multi-session disc (some of the CD-Rs I’ve used for testing got over 30 sessions burnt into them).
Running from a SD card also gets the nice benefit of not stopping the CD audio when loading data. However, this is more of a benefit to players than to developers, and I don’t think SD card readers are common amongst the majority of DC homebrew enthusiasts, at least not yet.
