BBC Micro / Electron Repton &copy; 1985 Superior Software / Tim Tyler Acorn Atom Repton by Kees van Oss, 2013

Introduction
Repton is the best-selling gaming franchise available for all Acorn machines. At least, it is now - never before available for the Acorn Atom, Kees van Oss was inspired by fellow RS coder David Boddie's reverse engineering of the Electron Repton level formats* and has successfully ported the original Electron release created by 15-year-old Tim Tyler and published by Superior Software in 1985. * See more reverse engineered games on the Useful Docs page. N.B. The modern Repton series continues to be developed by Superior Interactive for Windows and iOS platforms.

Atom
Port by Kees van Oss

The Electron version didn't use hardware scrolling so was a good candidate for porting to the Atom. It uses character scrolling so scrolling 8x8 bits. The playfield screen had to be adjusted and the layout rearranged due to the resolution difference but because the playfield is 18x18 instead of 22x22 characters, it scrolls faster and is fast enough to play at 1 MHz.
