If you downloaded a copy of Radiant Silvergun and that works, then you are good as far as the modchip is concerned. Originals should work fine.
As others noted, it seems that the problem is in the copy.
While the system may regard these as Audio Discs, it may believe they are games but will not play them due to regional incompatibility. If it displays a message that the disc is not compatible -- actual text -- then I would think the games are not properly region patched. I had this problem -- make certain that you are using the latest version of the Saturn region patcher (I mistakenly downloaded an early version which caused these failures). If the original image is built for two regions, make certain you patch it for two regions -- in my case, if its an AJ (Asian/Japanese) region, I'll change it to JU (Japanese/American). Close the patched image and reopen it in the Saturn Region patcher, simply to ascertain whether the changes you made are present.
Please note that my expertise only extends to Linux. I've burnt some things in Windows, and my mileage would vary from one program to the next. Alcohol did not burn the bin/cues as well as Nero, meanwhile Alchol worked well with the MDF/MDS (its native format, I believe). I would suspect there are probably settings to tweak on either program to make them work properly with different image types. Hopefully if you are burning with the same program you used to create the disc image, this won't be an issue.
You can also alter the region of the Saturn itself, using jumpers built on to the board. So, you could test your Japanese backups by effectively changing your Saturn to a Japanese model. If they work, there you go -- the patching is the problem. A special cartridge will do the same thing, if you have one handy -- perhaps your friend with the Japanese games will have an import cartridge you could borrow, as well. Again, this is just to test the quality of the copies and confirm its a region patching issue.
If you insert your discs into the system and it doesn't display an error message (such as "Disc Incompatible with this System"), then it truly does regard these as audio discs. In this case, make certain you are copying the disc as a mixed-mode (containing both data and audio -- although the game may not have audio tracks, in which case this is moot). Do not allow the programs to make any correction if it encounters errors. I believe it should be reading sub-channel data.
I've heard reports that using Karaoke as an image type sets the defaults perfectly. I've had no need to do this, so I'm not going to confirm that report.
If you still have problems, and if you believe its in the burning proceedure -- take some screenshots of your software's burning/ripping configurations. Take some more screenshots of the Saturn Region Patcher. Upload those so we can look for little mistakes/issues. And if the image is small, consider sending it to one of those free file hosting sites so others can take a look at it.
Cheers.
