Waldronate thats amazing, thank you so much
Knitted together, the meridians appear approximately elliptical(or quartic or something, but let's not get crazy), the parallels are evenly spaced. If I were forced to shove that into a mathematical projection, I'd go with a bizarrely interrupted Apian II. I don't know of any app that takes arbitrarily interrupted projections(of any sort) to reproject.
My suggestion, rather than trying to reproject or warp or slice-n-dice this map, would be to start with a blank page twice as wide as it is high. Treat that as equirectangular or geographical projection with equally-spaced straight parallels and meridians perpendicular to each other. On that sheet draw, by eye and imagination your best approximation to the island forms on the map, Remember to try to take into account the east-west stretching that will occur as you move away from the equator.
What you get won't be a perfect reproduction of the landforms in the existing map, but they are clearly, themselves, not a perfect reproduction of any land that could exist on the surface of any sphere.
Once you have a master in equirectangular projection, it's pretty easy to find something that will project that into a whole lot of other projections. FT Pro is good for that. If you want to get a lot more technical, Proj.4 is a good free app, but not necessarily easy.
EDIT: I should make sure there isn't a second page before I post .
Both Waldronate and Digger seem to have this well in hand. Neither of these are necessarily going to fit the intention of the map's author, but neither does the author's map so hey... it's .
This map is what happens when graphic designers do cartography . Graphic designers on this board are of course excepted. People on this board pretty uniformly have a respect for maps.

-Wilbur is Waldronate's. I'm just a fan.
When the maps all completed, what format would you recomend to redisplay it as a flat map and is the a programe to do it?
Well Done Digger! Do you have a heightfield (greyscale image)? I could generate a pretty detailed image with (grass/rock/etc) textures for you if you did.
Oh, Hi. I'm lurking around here now. Good to see more of your work.
Not knowing the first thing about any of the math involved in this I'm just going to say it looks very nice (and go stick my head in a book..a book about math..a book about math and maps...)
Even if I am correct, I would still advise you to follow your heart. This whole Cartographers Guild thing, it seems to me, is more about passion and skill and learning new techniques than it is about definitions and rules.
