Sonic GX - Sonic the Hedgehog looks stunning on the Amstrad GX4000 and Amstrad Plus

In the early 90's I had the pleasure of playing Sonic the Hedgehog on both the Sega Megadrive and Sega Master System. A game by Sega which featured a ring collecting blue hedgehog that could spin, run, jump and roll about at the fastest of speeds in a battle against the main antagonist Doctor Eggman, plus a number of other menacing enemies throughout each level. Now I'm sure many of you remember playing this fantastic game and probably still playing it to this day, but what you probably didn't know that as of today thanks to a heads up by our good friend XeNoMoRPH. NoRecess and team look to be working on a rather impressive Amstrad GX4000 and Plus conversion of Sonic the Hedgehog.

Preview 1 (November 01, 2019 )

Preview 2 Today!

According to norecess, he has said SonicGX was first previewed at the Alchimie XIII (1st of November 2019) as a work in progress game for the Amstrad GX4000 and Amstrad Plus Machines. He goes on to say the game will feature full-screen game-play at full-framerate (50hz) with approx. 52 colors on screen, and a Special Stage which is previewed in this brand new video above. Although Norecess does state "The gameplay is inspired (not a copy!) from the Special Stage as found in Sonic the Hedgehog 2 on the Sega Megadrive. Of course, it has been adapted to match the Amstrad GX-4000 limitations". So yes if you have a GX4000 or Plus, you owe it yourselves to play this upcoming game when it hopefully comes out 2024!

  1. I'm not an expert on the GX 4000 but the well known Burnin Rubber runs at about "12 fps" on it and this SONIC has literally "orders of magnitude" more on the screen even with parallax scrolling and it runs beautifully smoothly ..

    Ugh ?

  2. The graphics look good! Want to try it on my mod as my well.

  3. Makes sense this is possible though no doubt a technical marvel. The C64 port is pretty good and the GX4000 has a CPU 4 times as fast and loads of nice big sprites.

    1. Not quite true. The Z80 runs at little above 3 times the clock speed (wait states , otherwise it would be 4 times). The Commodores C64 is more effective, more like a Risc-processor and in real life the two processors are close in speed, maybe a little advantage for the Amstrad. But the custom hardware is better on the Amstrad plus/GX4000
