I stumbled across a video on Facebook promoting Bombjack GX. I thought it was a fake because the conversion was so perfect. Besides, Bombjack was one of my very first games on the Amstrad CPC back in the day, in the Elite compilation. HUGE congratulations. I'm really impressed
This is an AMAZING port, all but arcade perfect and perhaps displacing Pang and Donkey Kong as the best-ever coin-op ports on Amstrad hardware, but under emulation (on a Raspberry Pi here) there's a consistent glitch with bombs being in the wrong place, eg see the top left quadrant in this pic. They generally reset to the right place when you collect one in the same group, and it doesn't seem to affect Round 3 or Round 5. Bomb Jack Extra Sugar did not have this problem on the same system, so hopefully it can be fixed.
It's because the bombs are multiplexed hardware sprites and the timing is very precise. I only had four sprites free so when there are more than four bombs on a line the game is moving sprites left and right at the exact moment to appear like more than four.
Whatever emulator this is must not have completely accurate timing, which is a pity. I recommend using ACE-DL. I can't fix it because it's the emulator which has the problem. On real hardware the timing is correct. Please take it up with the emulator author - maybe they could use this as a benchmark...?
Hopefully that does the trick for you. I don't go out of my way to write games that break emulators so it's always a bit of a shame when they don't work correctly. I always test on real hardware to be sure.
Excellent !!! Witch emulator is the best to run this game ? I would like to use it with my Android smartphone and also a Raspberry Pie connected to my TV. Thx
I recommend ACE-DL because it supports the save function and it's the one I used to write the game. I've not tried running it on a Raspberry Pi... but apparently it can?

Nice version ! Thanks Anthony.

Am trying to figure how to install ACE-DL on the Pi, thanks for the info.

very good
Sorry for the delay, was waiting on Saberman's video :) - All done Bomb Jack GX - If you loved this Arcade classic back in the day, then check out this new Amstrad Plus and GX4000 version! https://www.indieretronews.com/2026/06/bomb-jack-gx-if-you-loved-this-arcade.html
I kind of wish you did keep all the extra features and game modes, playing with invincibility was great lol
If there is demand I could always consider a complete Extra Sugar version later. It just would not have been ready yet if I had.
Nice game!
Great game, thanks.

Excellent that you've created a page here! I hope you continue creating more CPC games, hehe! Cheers!
