Update on my SNES Turrican Project!

Hey everyone! Today I’m sharing a new milestone in the development of my SNES game based on Turrican. I’ve been working on the intro screens and running tests on the weapons and projectiles that Turrican can fire.

Right now I’m focusing heavily on sprite handling, animations, and projectile behavior. This part is crucial for the gameplay feel, so I’m doing a lot of testing to make sure everything runs smoothly and reacts the way it should on real SNES hardware.

Your feedback really helps as I continue refining the game.
Thanks for the support — more updates coming soon!

My monitor can do 1920x1200, so it should be fine. My a1222+ is actually hooked up to two monitors (different size but the same resolution), one over DVI to the motherboard, the other over DisplayPort to the Radeon. While the radeon is there the motherboard outputs nothing, and I only see the boot menu and kickstart loading progress.
I'll check what resolutions I have in the prefs.

Thanks

My current setup

• A2000 with 2MB CHIP, 3.1 ROM, OS 3.9
• TF536 with 64MB and IDEtoSD as boot drive (scsi.device)
• A2091 SCSI controller with 2MB (2nd.scsi.device)
• Plextor 12X SCSI CD-ROM, termination enabled, configured as ID 5

Essentially, I'd like to use the A2091 for the CD-ROM drive.  I don't really care about speed, I just need it to work from time-to-time.  Initially after installing the A2091, SetPatch was dying with a Software Error/GURU.  I found that disabling the 2MB onboard the A2091 (via jumper) fixed that issue.  I read about all sorts of issues with the TF536 and Zorro II fast ram, so I wasn't surprised.  I have enough fast on the TF536, so that is fine.  CD-ROM transfers are very slow, but they work.

The weirdness:

I'm now at the point where my system will only boot (in a reasonable amount of time) if there is a CD-ROM in the drive on boot.  Without a CD, the system sits for minutes and will eventually boot.  However, after that, when I load a CD in the drive and attempt to mount the CD0, the device will load, but it will not show up as a volume.  I'm assuming there is some ready signal from the CD-ROM that the A2091 requires.

I tried variations of the auto-boot enable/disable jumper on the A2091.  If auto-boot is disabled the system boots quickly, but when I mount the CD0 device, the device loads, but it will not actually mount the volume.

In short, if I leave a CD in the drive, have auto-boot enabled on the A2091, I can mount CD0 and the volume/media is accessible.  No CD in the drive on boot, no volume/media is accessible after inserting a CD and loading CD0.  With auto-boot disabled on the A2091, I can't mount the volume after boot.

It seems like I need to be able to re-initialize/re-scan the A2091 after the system is up?  Boot-up time is longer when there is a CD in the drive, so I'm really hoping to eliminate that requirement.  Note: I always manually mount the CD0 device so I don't use up buffers and stare at the unused volume on the desktop for 99% of the time I don't need it.

Any ideas?  I appreciate the help.

I have just released yet another demo (months ago I had shown a video, but I had not released the program itself):

The terrain is rendered by means of perspective-correct, wrap-around texture mapping. The city is rendered by means of solid bitmap zooming. The UFO is rendered by means of zero-keyed bitmap zooming. The screen uses PTDS, is 319x200 dots and employs the RGBWa color model.
On a stock Amiga 1200, the speed varies between 19 and 23 fps. On an Amiga 1200 equipped with a Blizzard 1230 IV mounting a 50 MHz 68030 and 60 ns FAST RAM, the speed varies between 67 and 80 fps. The fps fluctuations depend on the fact that the size of the UFO goes from very small (thus requiring only a few RAM accesses) to very large (requiring a lot of RAM accesses).
