Re: Time for a contest? Simplest maze-like printing..
Wow, I'd never realised it was possible to do inline assembly in GCL by using the addresses as byte values. It makes perfect sense, of course. I wish I'd known that sooner!

Re: A pull request (to be discussed)
I'm keen to see further ROMs in the "mainline" series. Naturally it's important that additions are well tested, documented, and agreed to be useful by the community (although what the process for that looks like, I don't know), and backwards and forwards compatibility is essential. If it w...

Re: ROMv6!
at67, is it your position that there probably shouldn't ever be any post-Marcel ROM releases continuing from the v1/v2/v3/v4/v5a series? Not at all, anyone is able to make pull requests for future ROM's, (as lb3361 has been doing). OK, thanks for clarifying. For what it's worth, I think we as a com...

Re: ROMv6!
at67, is it your position that there probably shouldn't ever be any post-Marcel ROM releases continuing from the v1/v2/v3/v4/v5a series? I imagine that there might be some more context to this than is evident from the two recent threads on this forum, but I'd like to understand whether this is to do...

Re: ROMv5 ?
There is already a SYS_Multiply_s16, written by at67, that multiplies two 16 bits numbers, returning the low 16 bits of the result. Of course one could improve its implementation in the future to make it much faster. Oh, right. I hadn't noticed that going in. I don't think my most recent bytes vers...

Re: ROMv5 ?
Hi, I support the idea that we should be working towards a new release, and think I agree that v6 is the right version to use. I'm fine with removing pictures, and adding other applications. But I wonder if perhaps we should switch making the version a label for a core set of functionality (fonts an...

Re: Racer.
Since you've been looking at Racer, I wonder if you have any insights into the inversion table in ROM page 10. I couldn't easily work out how it's being used from reading the Racer source, and the comment in the ROM source source ("Unit 64, table offset 16 (=1/4), value offset 1: (x+16)*(y+1) =...

Re: vCPU Questions and Necessary Details
Generally most of your questions can be answered by reading the contents of /Docs/ , however some more detailed answers are below. 1. What is the entry point of vCPU? The binary format for GT1 files (as understood by the loader application) includes a start-address, see /Docs/GT1-files.txt 2. Where ...
