Question about porting for different watch

[zlelik]

Hi,
I run your program for instinct3 in the simulator and it works nicely. Thank you for publishing it.
This is not an actual bug but rather a question.
I am trying to run your program for Instinct2, which has the same screen resolution as Instinct3. But I got the error while compiling the project that PRG file is too large. This is the error:
ERROR: PRG generated exceeds the memory limit of app type 'watch-app' for device id 'instinct2x': 212078 bytes.
Somehow, when I compile it for Instinct3, PRG file size is very small, around 73000 bytes.
but when I compile for instinct2, then it becomes 233324 bytes.
Maybe you have already tried to do something like this and know why it happens or why it is not possible at all?

Hi @zlelik sorry for getting back to you this late, thank you for checking out my port!

I am not an expert on the topic since I just played around with Gamin SDK for a month or so, and never tried building on different models of Garmin watch. My guess would be different optimizations levels for the different memory and resources of the Instinct2, plus the VM on the Instinct3 might be a newer version with different opcodes (?).

Anyway, I tried optimizing for execution speed and size a little bit using macros myself, but that didn't change much. But then I discovered prettier-extension-monkeyc which is an awesome tool to optimize the code further by stripping all type annotations, replacing enums with integers etc. plus can also optimize the bytecode a little bit.

Hope that helps, cheers!
