SainT Posted July 13, 2023 Share Posted July 13, 2023 (edited) The 7800GD has a built-in cheat system which lets cheats modify the RAM of the 7800 in real-time (per frame) and also the ROM image itself to enable cheats within games. This is all accessible from the cheats menu when you break into the game. To enable cheats, simply copy the 7800GD.CHT file into the root of your memory card containing games. Whenever games are launched, this file will be checked to see if there are any cheats available. These cheats were found and provided by Gent over at Emucheats, a big thank-you to him. 😄 You can also find and add your own cheats to the 7800GD.CHT file, further details of how to do this can be found in this thread: https://forums.atariage.com/topic/352992-creating-cheats/. Any cheats which people find and want to contribute, please post below and I'll add to the file linked on this post. The current list of cheats. Unless noted, cheats are for both PAL and NTSC. Crossbow [NTSC] Light gun calibration option Alien Brigade Infinite Ammo Infinite Health Asteroids Infinite Lives Basketbrawl Freeze Timer Player 2 Scores 0 Player 1 Scores 999 Centipede Infinite Lives Commando Infinite Bombs Infinite Lives Dark Chambers Infinite Health Infinite Keys Infinite Bombs All Upgrades Desert Falcon Infinite Lives Dig Dug Infinite Lives Invincibility Donkey Kong Infinite Lives Maximum Bonus Donkey Kong Jr Infinite Lives Maximum Bonus Double Dragon Infinite Health Infinite Lives Freeze Timer Fatal Run Freezer Timer Infinite Fuel No Damage Infinite Missiles Infinite Smoke Screen Infinite Machine Gun Infinite Oil Slick Infinite Shield Fight Night Freeze Timer Food Fight Infinite Lives Galaga Infinite Lives Hat Trick Freeze Timer Player 2 Scores 0 Player 1 Scores 99 Ikari Warriors Infinite Lives Invincible Infinite Ammo Infinite Grenades Joust Infinite Lives Karateka Infinite Health Kung Fu Master Infinite Health Infinite Lives (do not enable cheat until in game) Mario Brothers Infinite Lives Mat Mania Challenge Freeze Timer Instant Win on Pin Player 2 Can't Win Mean 18 Golf Always First Stroke Midnight Mutants Blood Always 100% Pure Infinite Health Motor Psycho Freeze Timer Ms Pac-Man Infinite Lives Ninja Golf Infinite Health Infinite Lives Infinite Throwing Stars One-on-One Basketball Infinite Shot Time Freeze Overall Timer Player 1 has 999 Score Player 2 has 0 Score Planet Smashers Infinite Lives Infinite Shield Infinite Earth Shield Rampage Infinite Health Robotron 2084 Infinite Lives Scrapyard Dog Infinite Lives Infinite Shields Infinite Cans Infinite Magic Cans Infinite Bombs Tank Command Infinite Lives Infinite Energy Infinite Ammo Infinite Fuel Tower Toppler Infinite Lives 7800GD.CHT Edited July 13, 2023 by SainT 9 5 Quote Link to comment Share on other sites More sharing options...
+MattelAquarius Posted February 16 Share Posted February 16 I absolutely love this feature! The GameDrive is awesome without it, but this will really help me enjoy the games more, particularly with friends who aren't as well practiced on the 7800 games. After excitedly jumping from game to game, trying the cheats, I noticed an issue with infinite lives on Ikari Warriors. The number of lives continues to show nine, but I get a game over after a few deaths. Is it just me? Invincibility and unlimited ammo work properly. Going to have a blast with the games this weekend. My brother is going to stop by and slam through some games with me. I am amused at how giddy I am with this new "toy". Thank you! 1 Quote Link to comment Share on other sites More sharing options...
SainT Posted February 17 Author Share Posted February 17 Awesome, glad you’re enjoying it! I’ve not had much feedback on the cheats, so it’s nice to hear you’re enjoying them. The cheats were provided by Gent over at emucheats, so it could well be that there is an issue with that one. I’ll have a look when I get a chance!

+MattelAquarius Posted February 17 Share Posted February 17 No worries! After some more game time on other titles, I quickly realized that playing with the cheats is a bit of fun itself. One must learn when to enable and disable. For example, if I start Double Dragon with the cheats enabled immediately, you cannot progress beyond the initial open garage door screen, but if you first scroll the screen before engaging, they work just fine. Other games (e.g. Kung Fu Master, and Dark Chambers), you may not progress to the next level in a game until you disable one or more cheats, because the game wants to award you points for remaining health (or some other criteria), but since the health is infinite, it can never finish. LOL Simply disable the cheat to proceed to the next level, then re-enable. All in good fun, so please don't devote much time to this "issue". I'll give Ikari another try, to see if there's some similar trickery to the infinite lives cheat. My 7800 has never looked, sounded, and played so well. Thank you for this amazing fun-enhancing genius device! 2 Quote Link to comment Share on other sites More sharing options...

Hi MattelAquarius, Yea this is a known issue that SainT is looking into via the ability to have notes visually showing instructions on what to do. Also i am always updating the file with more support (Homebrew currently) and the the cheat file is always up to date via my Retro-HQ-7800-GD-Cheat-Tool Cheat file 1 Quote Link to comment Share on other sites More sharing options...

I will look at this and see if it is because of the way SainT utilizes the RAM Cheats, or if i can adjust it better. Is the NTSC or PAL btw? Also, if you would like to report any cheat issues in real-time by all means come join us on the 7800GC Cheat Discord Edit: Ok i have updated / Fixed your issue with Ikari Warriors and you can get it Here. Could you try it and let me how you get on in 7800GC Cheat Discord? Thanks. Edited April 17 by Gent 1 Quote Link to comment Share on other sites More sharing options...

Another minor issue I will bring up over at Discord, is the cheat for "Infinite Energy" in Tank Command. You may want to consider removing that one entirely, because it actually hinders the player's ability to adjust the distance of their shots. By default, the player already has "infinite" energy in this regard, as they can adjust the shot distance from minimum to maximum at a whim based on their current situation. However, with the cheat enabled, the player can only fire shots at the maximum distance, which could be considered a hinderance or handicap to the gameplay. 1 Quote Link to comment Share on other sites More sharing options...
