I came across this project by chance, which has recently also integrated support for the MEGA65. It sounds very interesting and makes a good impression at first glance.
Turbo Rascal Syntax error, “;” expected but “BEGIN”
Quote“Turbo Rascal Syntax error, “;” expected but “BEGIN” (Turbo Rascal SE, TRSE) is a complete suite (IDE, compiler, programming language, image sprite level resource editor) intended for developing games/demos for 8 / 16-bit line of computers, with a focus on the MOS 6502, the Motorola 68000, the (GB)Z80 and the X86.
Due to lack of time, I did not deal with it very intensively, but I wanted to at least introduce it and show you a few very first steps with it.
First, of course, you should download it. Versions for Windows, macOS and Linux can be found here:
After starting it, you can choose one of the many tutorials. Ideally in our case, of course, "MEGA65":
You can enter the desired emulator in the settings. I chose the xmega65 from hernandp because it also implemented a lot of VIC-4 things.
First I loaded a raster program (07_rasters.ras) from the tutorial and then let it compile "RUN".
Then the selected emulator is started automatically and the generated program is integrated and started. Worked out pretty well:
Then I quickly load (01_hello_world.ras) and modified a little the obligatory simple "Hello World" with a few "color effects".
Looks pretty good so far! 
By the way, the project for the C64 was presented here in this older thread. The good news is that it now supports the MEGA65 as well.
It is certainly worth a closer look. For example, I haven't found a command on the fly how to get keyboard entries such as an "INPUT A$" like in BASIC. But there is certainly that somewhere in the project. 
Overall, I like it very much and it's very interesting!
