>I've tried that old program without much luck.
For new MW forum visitors not aware....it dates back to 2014 with Marc Lafontaine's graphics ripper program that was uploaded back then and should be able to be still downloaded at this time. time for PSE Desert Patrol mini thread *edit* 10/02/14 Attachment: rip081.zip 152 KB (17 downloads)
https://www.mameworld.info/ubbthreads/sh...part=1&vc=1
*excerpt of 2014 post giving brief usage info of how to work with ripper* -- For those that have seen data images for Bazooka and wonder how they were generated, it would likely be from Marc Lafontaine's program called Ripper which can be grabbed from here as a zip file attachment. The zip file also includes same instructions I typed here for how to view PSE game images and an image of airplane targets from Desert Patrol.
Marc Lafontaine contributed to MAME during MAME's early years such as this entry for release .13 from 1997.
0.13 ---- - Marc Lafontaine submitted a new palette for Zaxxon.
The program has capability of viewing images off of some roms of 1970s and some 1980s era arcade video games. For an example of describing how to view images of either PSE Bazooka or PSE Desert Patrol, load a file where it says file1 and press CP. Set the width to 32 and in the algorithm you have to change the bits to reverse order.
The 'change the bits to reverse order' might not make sense, but what this means is the user presses the algorithm button and then a different screen appears. User presses the Clear button, and after doing that then click on number buttons in direction of going from right to left side (ie 'reverse orer').
Once that is done, then press okay, then set width to setting of 32 and then press the CP button while Desert Patrol's file 'L4' is loaded as file1.
The images of various airplane targets will then appear on the screen, but in an upside down position. The upside down snap image, can be fixed by using a paint editor program to have the image rotated to a right side up position. -
Assuming any user has roms for either Exidy Death Race or Robot Hunting and have already downloaded Marc Lafontaine's graphics ripper program from old 2014 post. I don't have either rom set myself.
Experiment with proms type 82S123: 256-bit (32x8) TTL bipolar PROM with tri-state outputs
Try Robot Hunting rom set since that is considered valid compared to Death Race rom set.
Load up any of these four files within the Robot Hunting rom set to see if any images are visible. Experimenting with ripper control settings may come into play. Good luck if anyone tries to work with extracting any images from Robot Hunting with these four rom files: 6331-1.e7, 6331-1.r7, 6331-1.t7, 6331-1.g7

For Sega Fonz fans, there are three roms that the Fonz pdf logic schematics file describes as 'shape' proms. Logic schematics for Fonz is vague so it will be a guessing game with any of the three files: ic86.86, ic87.87, pr-08.50
Hopefully some image can be found/generated using ripper with Fonz romset.
