TI 68K / Delsgolf (TI-89) Update
« on: May 24, 2015, 11:14:37 am »
I have somewhat recently started to optimize Delsgolf ( that first person shooter for the TI-89 ) again and want to release it now to a more wider audience than myself. Delsgolf now also has some sort of sound ( link port stereo, like polysound ) and the data file has a slightly smaller size. The game assets ( map, textures, etc ) have remained unchanged.

I have attached a release candidate to this post.

If you want to know what you are getting with Delsgolf, the older version with a slightly more verbose description is still here:

I would also be very happy if someone could tell me how to not make Ti-Emu screw up the screen because of grayscale emulation, as can be seen in the ticalc link animated screenshot.

TI-Nspire / So I am porting Quake to the Nspire...

So with the recent release of ndless for 3.6 I have chosen to aquire a TI-Nspire CX and do some programming.

To get a feeling for the platform I have further chosen to port some first person shooter from 1996 and in nspire_emu it runs pretty well. However on my OS 3.6 Nspire CX CAS it first did not run at all and once I removed all printfs it ran but was kind of slow compared to nspire_emu. So I have some questions ..

1. Does it matter if I try to printf to the console ( serial port ? ) and there is no receiver connected ? From my program failure it appears so but I rather have the printfs() in so I can debug using nspire_emu. Are there other pitfalls that do not occur in nspire_emu but do on real hardware that can cause something like this ?

2. Either my Nspire ( hardware revision M ) is slower than normal Nspires or nspire_emu is faster than the actual hardware. As with porting some game most time is spent adapting to the new platform ( read optimizing ) I am wondering if nspire_emu is even cycle accurate or if I can only rely on benchmarks run on the real hardware.

So this is all that is going around in my head now.. I'll try to attach some photo to show my current progress.

PS: To skip my introduction in the introduction board I am the guy that did that Delsgolf FPS for the TI-89 last year.

*edit* Changed Title
