Well, I've been busy in the background for the last while.
I left my job on 25th September and started a new one on 5th October. During that downtime, I decided to get started on rewriting my GUI in Java, mainly for the cross-platform capability. I wasn't sure if I could do it but less than a month later, I have a mostly working build and feature parity with the current VB6-based version. However I don't feel ready to release it yet, it's a bit rough round the edges. I've redesigned it with a tabbed interface to make it look a bit less daunting, and also redirected the console output from hacktv into the application. It works pretty much perfectly on Ubuntu and Fedora but I'm having issues on Windows with the console redirection. For some reason, the console text only appears after hacktv exits. I also tried a simple "Hello World" written in C and it does the same thing. But, Windows-native stuff like ping.exe redirects fine. So I'm a bit lost! I had the same issue when I tried to do this with VB.NET earlier in the year too.
Anyway, here's a screenshot of my progress so far, this is running in Ubuntu. JRE or OpenJDK 11 or later is required.
