Video: Tower 57 playing on the "Tabor" motherboard (update)
In a blog entry Hyperion shows the crowdfunded shooter Tower 57, which will be also released for AmigaOS 4. Daniel Müßener is developing the port for OS4 and has created a special version of the game for the Tabor motherboard ("A1222") presenting the current stage of development. A video showing the game on an AmigaOne A1222 gives an impression. The developer wrote, that the version for the Tabor would run "a lot faster than on a sam460ex" - explaining: "Tower57 is some kind of special case though, primarily because I do pure software rendering inside this Amiga port, so the program doesn't have to comunicate floats directly to other libraries, roughly spoken."

Hint of the editorial staff: The processor QorIQ P1022, part of Tabor, uses a FPU which is incompatible to most of the Power Processors, also that ones, which are used in the AmigaOS 4 computers. In order to make it compatible to existing AmigaOS 4 software, the operating system has to have a compatibility layer, which currently none of us knows any information or details. Therefore it is not clear if this special Tabor edition of the game was created due to speed or compatibility reasons.

Update: (17.02.2017, 15:00 Uhr, cg)

As one of our readers in our German comments has pointed out, there are more information on the YouTube website concerning a normal build of the game:

"The "normal" Tower57 FPU build works too on the Tabor btw. In that case, as with all other FPU-using programs, the OS' current compatibility backend kicks in and "translates" each and every FPU-opcode into something the Tabor likes. Interesting enough: even then the Tabor is so powerful that it's still playable (about 20fps where the sam460 reaches about 30fps)." (cg) (Translation: dr)
