petit chou

Thank you both so very much for your informative (and encouraging!) replies. I'm excited to get to work on this!

Hey everybody, I apologize if anyone has asked these question before -- I tried searching with limited success. I am working on writing a roguelike for the INTV, now using IntyBASIC ideally to be part of the contest. The problem is that the program I want to write, including its art assets, is kind of huge and unwieldy and I have genuine worries that I'm not going to be able to cram everything I'd like into the address space. The IntyBASIC manual has this to say about the subject: The memory_map.txt file in the SDK, however, has what appears to be a much larger selection of addresses: So, the questions I have: Does IntyBASIC attach to the areas listed in the memory map but not listed in its documentation ($4000-$4FFF, $7000-$7FFF, $8040-$9FFF) in order to store variables? What about its prologue/epilogue routines? Clearly those routines have to go somewhere, but I'm a little confused about what determines where they show up. The prologue looks like it starts at $5000 and it looks like the epilogue is using some of the address space in the $4000 block to store some routines, but is there any extra space that can be squeezed out of these areas? There is no ORG directive at the beginning of the epilogue. Do those routines just go wherever the compiler's location counter happens to be pointing when it goes to include this? Will I need to worry about the epilogue writing itself to bizarre or inappropriate places if my code stops near one of the memory boundaries, or will the BASIC compiler make sure that doesn't happen? Where is the entry point for IntyBASIC programs? I'd like to make a custom title screen if possible. If I start my program with ASM ORG $7000, will it begin execution there and bypass the EXEC? (Does IntyBASIC need the EXEC?) I noticed that there's some code at $4800 in the epilogue pertaining to the Intellivoice, but it looks like it may not be present if the Intellivoice isn't used. (I realize half the reason for using BASIC instead of assembly language is to not have to worry about fiddly details like this, but I want to make good, appropriate decisions about how to organize my program and figure out what all I will be able to include as far as assets go before I begin any major coding.) Thanks a bunch!

Thank you all so very much for your extremely helpful replies! I am continually amazed at how encouraging and supportive this community is.

Hi there, Does anyone have any good information on the exact structure of the expected ROM header in an Intellivision ROM? I've found examples that strategically pass zeros and ones (like the ones in the jzintv documentation labeled "EXEC friendly ROM header") but I would really like to know if possible more about what exactly is supposed to be here and why. Does anyone here have any leads or know where I might be able to find this sort of documentation? Any help would be appreciated. Thanks a bunch!

Thanks so much for your swift reply. I'll look forward to seeing it happen!

Is there currently a way to use the JLP save and restore functions within IntyBASIC? I'm doing some preliminary planning for a game I'd like to write for the Intellivision and having this feature available would be extremely useful. Thanks!
