In Search of 15C+ ROM image

The video is excellent to clarify for new Voyager users how the expanded memory is used and can be easily verified on an LE, thanks for creating and sharing this here dmh! . The extra info on how to make the file mods is also clear and helpful for folks new to this stuff, though it indirectly reveals JFG's clever hints on file format .

Also, I see a lot of folks clamoring to modify the older f/w release that precedes the final f/w version with the PSE bug, and these folks need to keep in mind that the older versions also have several bugs in them, some of them significant enough to warrant being fixed, which is how the PSE bug was introduced! I was not involved in the 15C+ testing at the time, so have no notes about the reported bugs and planned corrections, but I recall Tim talking about them at the time and he cautioned that the earlier bugs were much more serious, and affected calculating results, rather than the more cosmetic nature of the PSE bug, which can be worked around easily (e.g. using [R/S] in place of PSE, or even removing PSE completely). So it probably makes more sense to use the latest f/w and deal with the PSE bug by slight mods to the programs you'll use.
