At the end a Max robot is supposed to follow you down the elevator shaft and then kill you off. Glad people can get a peek at the special CAX rom version that Jess Askey made just for the show. So that was you recording me playing MHPE on Jonathan Koolpe's machine (6:31). Improved Self Test and EEPROM based settings (DIPS options) A homeworld that is true to Owen's original vision.Ĩ. 8 new levels after the existing 16 levels.Ģ. Here are some things that are part of this release:ġ. In some ways, it is sort of a 'directors cut' of Major Havoc with many of the features that Owen Rubin on twitter) was not able to put into the original release due to various reasons around hardware, time, and budgets. It is an enhancement which basically adds new features to Major Havoc that were not in the original release. What is this exactly? Major Havoc: The Promised End is a rewrite of Major Havoc from Atari. who would have thought that 6 words could start a journey that lasted over 35 years. please submit bugs on the github site if you try it out!! I try and release ROM images every few weeks but I won't post for each release here unless folks want me too, just keep watch on the site. I think that should be a good start for most of you to get started. 8 new levels which will be contest driven, more info coming soon. CAX hacks - two new levels and MAX robotsĢ. Lots of tweaks to make gameplay 'accentuated'ĥ. This game is incomplete, if you were at CAX, there are a lot of new things here, but this is still pretty early.ģ. Specifics of the ROM patch on the GIT site right now.ġ. NOTE: I created the patch files using a Windows 10 build of BSDIFF/BSPATCH so Im curious if folks on other platforms have issues with the patches or if they work fine. Patch files and instructions on how to patch your Major Havoc v3 ROM images to play the new game. A custom build of MAME (windows 64-bit) with the new mhavocpe driver until I can get my driver into the main MAME release cycle (should be next version of MAME)ģ. Instructions on how to modify your PCB to run these ROM'sĢ. If you are interested in following along with announcements and bugs etc, I have a GITHUB project for this which has all of that and more.ġ. I mentioned during the presentation that Owen, Scott and I did that I would put some info up here about the game and how to get BETA ROM images so here goes. Im finally back to Colorado after a 3000 mile round trip with the Alpha One cabinet. it was great to meet many of you at CAX this past weekend. Have you measured the AC ripple on the DC voltages? Definitely check them, as it's easy to do, and rules stuff out.Hi Folks. A bad crimp can cause an open connection, as well as a broken pin inside the connectors (though this applies more to the connectors on the AR, which we suspect are ok if you've verified them in other cabs.)Īre you getting hum without the game board plugged in? Can you provide more detail on the hum? The cab should be silent without the game board plugged in, else it's a power or harness issue. It's possible for the LM324 audio output amp on the game board to go bad, but if you're seeing it on two separate boards, that's probably not the case.īe sure to check wires, remembering that just because there's a wire there, doesn't mean it's actually connected, so tone everything out with your DMM. Well, next would be to verify that you have an audio signal going from the game board to the AR. I have never attempted to use a conversion PCB in a dedicated cab and thought that I read all there was on using one in this application but it appears that I am missing something.Ĭan someone shed some light on my current (one of many) predicament!?!? The board that I am using is a working pull and to be sure, I tried another known good PCB with the same results. I tried 2 different known working AR II's with the same results. ![]() I checked P20-8 and P20-9 (SEC connector) and they have continuity to P7-8 and P7-9 (at the ARII) and appear to be OK. ![]() I even tried disconnecting the speakers and tried one set at a time (upper / lower) just to be sure with no difference in "hum". I checked the harness at P8-3 to P8-4 (unplugged from the ARII) and get about 2.5 ohms through the speaker connections, no shorts there. When power is applied, I do not get the initial "boom" and there are no sounds during game play, all tests show OK.
