This isn't really a mod, but just the original excellent @Ross DX layout added with the @johnparker007 hacked v1.0 ROM. You can read all about the development of the hack here: Basically this hack puts back in the emptier from the original v0.4 £15 release ROM. The trick is to play for barcode wins from nudges, moving the reels into let 'em spin configuration. Barcode wins are free, and do not update the compensators. The best barcodes to take are 3-2-1 and 3-1-2. If you take 3-2-1 you can hold down all hold buttons (1,2,3) to get all the way to a £15 JP repeater. Enjoy. Massive thanks here to @Ross for the DX that makes it all worthwhile and @johnparker007 for the genius.

The existing @dad and also @Multi Retro Man DX layouts are the best versions of Donkey Kong from a graphics perspective. We had been using those DXs to test a hack to the earliest Donkey Kong ROM over on the ROM hacking forum thread posted below. The purpose of the discussion was to try and hack the earliest ROM we have to patch back in the original skill nudge cheat. Massive kudos to all of @johnparker007 efforts with the hack. The video below from @Chopaholic will explain things much better than trying to understand the entire ROM hacking thread. The issue we had with both of the latest DXs is that they still have cash values for the £5 game. I doubt these DXs will be improved again but I wanted to also have a version of the DX in my playable set which does have the correct cash values. Here is a mod I have done for an older DX done by Andy T (a DX done some 21 years ago!!) I am sharing this mod here for anyone who would enjoy it as another option to play but please remember graphically the latest DXs are much better. Thanks to @dad @Multi Retro Man and Andy T for all the hard work originally. This type of mod is simple to do in comparison to a full DX. Game Information Note: The patched/hacked ROMs do not require you to hold the Cancel button down to activate Skill Nudges Donkey_Kong_(Maygay)_[Dx08_10jp].gam - This game file runs the SA7-103 (v1.1) ROM as normal, with no hacks. Donkey_Kong_(Maygay)_[Dx08_Patch1_10jp].gam - This game file runs the SA7-103 (v1.1) ROM with @johnparker007's original hack. When offering natural nudges, it will always give you the Skill Nudge type. Donkey_Kong_(Maygay)_[Dx08_Patch2_10jp].gam - This game file runs the SA7-103 (v1.1) ROM with @johnparker007's alternative hack. This offers Skill Nudges after every reel spin. Donkey_Kong_(Maygay)_[Dx08_Patch3_10jp].gam - This runs the SA7-103 (v1.1) ROM with a further revised (fine-tuned) hack based on 'Patch1'. The frequency of natural nudges is increased, which always gives the Skill Nudge type. 'Patch3' is now very close to the behaviour of the original emptiable v1.0 ROM with Cancel held down. Therefore 'Patch3' is my recommended game to play to re-create the original emptier behaviour. DX Changelog .
