Asmusr

Would it be possible to develop a faster drop in replacement for the TMS9900 (like the F18A GPU), cut the power to the old chip, and piggy bag the new chip/pcb on top?

Yes that would work for me. The problem with the long warning is that I wouldn't notice any other warnings. 🙂

The two bytes that should be swapped are at offset >1090 in the GROM. But I wouldn't dare to post a fixed version. 🙂

I'm getting this warning each time I run the assembler because I use Magellan to generate my graphics, and that produces a label for every pattern or color. Would it be possible add a flag to suppress the warning?

Maybe I'm dreaming, I thought Paul Urbanus posted a few times here on AtariAge recently, but I can't find any trace of him now. Maybe I remember when he commented on the Mega Demo on YouTube? Anyway, I thought it would be fun to ask him if he was aware of the typo.

I have never actually noticed that before.

It works for me using Edge.

Knight Lore can use two buttons if they are mapped to the fire buttons of controller one and two.

So it appears I borrowed your dad's music for my Flappy Bird game. Thank you.

Thanks. I can reproduce the issue if I move into a square that would end a path and then retract just before the area is filled. I'm not sure if I can fix that issue or it's just something to avoid permanently.

I made a change that should prevent you from getting a split TIX when there's only one TIX. I don't know how to reproduce the original issue, so I'm not sure that the fix is working, but I did not have any issues after playing a number of games. Another issue I think people have mentioned is that you cannot finish a path at the corner of an already filled area. For instance, in the illustration below the path of Xs cannot end at the indicated point, and it cannot continue down the side of the filled area either. You have to make a left turn and end the path another place perpendicular to a wall. This limitation is not a bug but the only way I could ensure that surrounded areas are always fillled. ##### oooo# oooo#XXXX oooo# X ##### X XXXX tix.rpk tix8.bin

This tileset is re-using some of the ideas from the F18A tileset I posted about a year ago (e.g. the stairs), but it's now good old 9918A only. I'm considering if I want to use this for a new (scrolling - but not smoothly) platform game, or I want to try make another, perhaps ancient Egyptian, tileset. Hmm, perhaps both.

Thank you for trying out my unfinished game. @Opry99er please change the title of this thread to January Centipede.

It's really impressive- in particular since you are is not using the 32k. I would like to know more about your scrolling routine and how you load new patterns on the fly.

Probably just a typo in your post, but in the second line you use an O instead of a 0 in R0.

Thank you for the bug reports. It good to have any issues recorded should I decide to finish the game at some point.

So it's only for when you load (multiple) object files using E/A#3?

Sorry, but what does RORG do?

I have never used RORG - with or without an address.

Maybe you can get some ideas from my source code? You can see this demo in https://js99er.net under Software/F18A specific/GPU PIX lines demo. pixlines.a99

Not only subscribers. I just changed the title of one of my very old threads. But in the other forum you only have one hour, I think.

I see the .bin files.

A 256x192 bitmap is using 12K, so you cannot use anything below 0x3000 for other things. CPU registers and VPD registers are different, if that's what you mean. Why 0x15? This is overlapping the bitmap. 0x1b00? Not sure what you're trying to do here? 5x0x800 = 0x2800 (overlapping full screen bitmap) You are not setting VDP reg 1, are you sure it's OK?

I don't think so. It can only import character images, e.g. PNGs.

I also forgot that IDLE is part of the standard TMS9900 instruction set.
