Lightgun tester - help wanted

Post by KanedaFr » Tue Nov 08, 2016 12:22 am

Hi,

I was busy lately.
I mainly worked on lightguns : how they work, how to handle.
The result is a wip library, ready to use, and this ROM is the libray tester.


http://gendev.spritesmind.net/files/md/ ... r_v1.0.zip


While most of the part of the library was checked and validated in end of October'16, on the RGC2016, some improvments were made since then.
Problems is I can't check it again:
- Values are very unstables on Fusion (I suspect it patches values according KNOWN gun games loaded)
- I didn't test it on RetroArch (unable to launch it on my PC).
- My CRT TV died 1 year ago.
Hence this ROM which should help me to detect and fix any bugs !

So please, if you have a gun and a CRT, please launch it and get back to me with


ROM version : 1.0
Genesis model : 1/2/3/Xeyes/wondermega/...
Genesis region : US/EUR/JAP
TV : Brand, size, region and any other info (or url)
ROM player : EverDrive (which one) / MagicDrive / flash cart / repro cart /.....
Gun tested : Justifier / Menacer / Phaser
Title - Gun auto detect ? OK/KO
Calibration - min raw X : postive value you're able reach pointing gun left
Calibration - max raw X : postive value you're able reach pointing gun right
Calibration - min raw Y : postive value you're able reach pointing gun top
Calibration - max raw Y : postive value you're able reach pointing gun bottom
Calibration - color : is there any background color the gun isn't working on ?
Calibration - auto calibrate : did the auto calibration let you shoot 'almost' perfectly on target while testing or not ?
Testing - cursor position : do you feel the cursor is too much on right / top ? a lot (pixels size if you're able to tell it) ?
Testing - cursor movement : is the cursor movement smooth enough ? too much ?
Testing - cursor on top : does the cursor reacts strangely when you aim to screen top ?
Testing - cursor on right : does the cursor reacts strangely when you aim to screen right ?
Testing - cursor on left : does the cursor reacts strangely when you aim to screen left ?
Testing - cursor on bottom : does the cursor reacts strangely when you aim to screen bottom ?
Testing - cursor exit : does the cursor ends at the correct position when you aim out of the TV ?
Testing - cursor shaking : not using average value, does the cursor 'shakes' a lot (not stable enough) ?
Compare : works worst/best/same on Menacer6in1 / Lethal enforcer
Comments : any detail or any feeling which could help me improve my code

added the .bin version into the zip, since .smd isn't handle by every flash cart

perhaps it will help to rise the number of testers from.....zero to more

it seems we won't see a new lightgun game soon :(

I don't have a CRT, but the MADE (local video game museum) does. Not sure what they have in the way of light guns, but I'd be surprised if they didn't have any of the Genesis ones. I'll try to remember to bring my MED there on Saturday so I can give this a spin.

ROM version : 1.0
Genesis model : 1 (appears to be a VA7)
Genesis region : US/EUR/JAP
TV : Panasonic, small (not sure of exact size, probably no more than 13"), NTSC, says TBM2A22309 on front panel
ROM player : EverDrive (unsure, forgot my MED so just using what they have)
Gun tested : Menacer
Title - Gun auto detect ? OK
Calibration - min raw X : 63
Calibration - max raw X : 254
Calibration - min raw Y : 7
Calibration - max raw Y : 217
Calibration - color : red and dark blue seemed to have the worst tracking
Calibration - auto calibrate : Calibration screen seemed very broken. Seemed to advance all by itself (possibly a button detection problem?)
Testing - cursor position : cursor is too far to the left, goes offscreen on leftmost edge and can't reach the right edge of the screen (possibly due to calibration problem)
Testing - cursor movement :OK with certain colors, but not all
Testing - cursor on top : Fine until I hit the top edge of the display, jumps slightly before stopping, but otherwise OK
Testing - cursor on right :Can't reach the right edge of the screen, but otherwise seems mostly fine
Testing - cursor on left : Cursor goes offscreen, but otherwise OK
Testing - cursor on bottom :Fine until I hit the top edge of the display, jumps slightly before stopping, but otherwise OK
Testing - cursor exit : Jumps slightly but otherwise ok
Testing - cursor shaking : Not sure which mode is default, but the non-default mode had the cursor jumping around a lot
Compare : overall seems worse than Menacer 6 in 1
Comments : I assume that the X is supposed to appear when the fire button is pressed. This appeared to be having a lot of false positives.

Min max values were not from calibration screen, but the text on the bottom.
Text was cut off by one letter on left (R in raw and C in Clean) and the line after Clean was mostly cut off on the bottom

ROM player : EverDrive (unsure, forgot my MED so just using what they have)
Gun tested : Light Phaser
Title - Gun auto detect ? No - had to manually select, reports "NONE / UNKNOWN"
Calibration - min raw X : 37? (too much jitter in raw value to be sure of last digit
Calibration - max raw X : 235? (too much jitter in raw value to be sure of last digit
Calibration - min raw Y : 5
Calibration - max raw Y : 218
Calibration - color : red didn't really work at all, other colors seemed fine
Calibration - auto calibrate : Calibration process seemed fine, resulting cursor position was off (see below
Testing - cursor position : cursor is too far to the left, goes offscreen on leftmost edge and can't reach the right edge of the screen (possibly due to calibration problem)
Testing - cursor movement :OK with certain colors, but not all
Testing - cursor on top : Fine until I hit the top edge of the display, jumps slightly before stopping, but otherwise OK

Testing - cursor on bottom :Fine until I hit the top edge of the display, jumps slightly before stopping, but otherwise OK
Testing - cursor exit : Jumps slightly but otherwise ok
Testing - cursor shaking : Not sure which mode is default, but the non-default mode had the cursor jumping around a lot, but much less than with the Menacer
Compare : generally seems fine apart from the aim being a bit off
Comments : No false positives for firing

ohh...that much ?!
it's totally broken then :(

Thanks for the report, it confirms the strange behavior on top and the red color issue (try to shoot ship on T2, you'll get the same problems)
I was aware of the cursor offset, just wanted to know if it was my guns or standard.

Very surprised it got so much wrong with the menacer, I spent so much time fixing it ...it seems I broke something.

anyway, thanks for these reports, very helpful.

And good news : I found a CRT screen, to test v1.01 myself so I won't bother anyone with my requests in the future.

So wait a minute, the Master System gun is more accurate?
Sik is pronounced as "seek", not as "sick".

Menacer 6 in 1 seemed to actually work quite well, but to be honest I only tried it fairly briefly to test whether the gun was working properly. It's possible the tracking was generally equivalent, but I noticed the limitations more with your test ROM as I spent more time with it. Button handling was definitely broken though.

The Light Phaser seemed more sensitive to the background color (red worked poorly on the Menacer, but it still was somewhat useable. On the Light Phaser it didn't work at all), but it did seem a bit smoother on colors it worked well with, especially with smoothing/averaging turned off. That is a fairly subjective observation though and it's possible my experience was colored by the issues with the fire button. Additionally, the fire button issues mean that the calibration step was not done properly so that may have contributed as well.
