ok i finally test all sgm game that i have on 2 standalone adam and they all work... the game i didnt test yet since i lent them to a friend are gradius and peinguin adventure from opcode.. i will go get them and see if they work... so maybe some game will not work in the future but for the previous release they seem to work perfectly... i dont think i will do more test on this.. you build it if you want... if you want to be sure 100% compatibilities get the new phoenix or a sgm...

i know how to add the 8k ram as you can see in the short video... you can also see how many ic's it require to do it so if i add the 8k ram i should put the 24k too so it's a ttl sgm and my ass get kick out so i wont do it... is there other games that require the full 32k of ram?? i will try every game that i have to see if there is some that dont work on the adam with the ay only...

expansion

you are the only one who can test it since the game is not released yet... i can ship this one to you if you want to test... i made this to see if its possible to only use the ay on the adam and yes it works for the part i can test... it also work on the coleco for meca 8 and 9 since the game dont check for extra ram... i wont sell or build them for people its there for anybody who want to try it... let me know if you want to try it...

here the sound chip enhancer for the adam computer.... it give you the missing sounds from the sgm game on the adam it use only ttl chip so nothing to program very easy to build... i only test on ntsc system so i dont know if it work on others region system.... here the gerber files enjoy AdamSoundChip.zip

i bought the first one on ebay when opcode was mia and already preoder2 from the second run.. the last one i bought its for the new lable and the new box

that's true i have 4... 1 from the first run 2 from the second run and 1 clear case from the last run...

castle and castle exelent work on the adam too

at that time Ed was mia and i wanted to play sgm game ... i didnt know fuck all about z80 and address decoding so they help me to add 24k ram to my coleco...

i never tried on the c100 sice it's after the c88 where is the jonction of the exp port sound and audio out from the sn chip... but i know for sure the sound will be low with the sgm cause my first coleco had this av mod and i had to move the wire to the c88 to have the correct volume with the sgm

you should try at the c88 cause on the pin 7 you will get low volume with the sgm

maybe someone will do it... to make it 100% compatible with all the adam add on it will require a lot of time and effort not even sure you can intercep the video signal on the adam.. sure it work on the coleco with the sgm... for me its the end of the story...

the cost is very low exept for the f18a him self pcb print in china around 4$ xilinxs 2 or 3 $ on ebay 40 pin socket under 1$ 60 pin edge connector can be ordered on ebay 10 for 15$ f18a new version?

i have this done and ready but its for me only cause i will never work on another colecovision project im done and learn the hard way here

it's possible to run the f18a from the exp port of the colecovision.. not sure about the adam stand alone

since most of us have multiple system we can play the game.. do you have this game??? probably can you play with your f18a coleco ... me when i turn it on i get the f18a error screen thant i turn it off and on fast than the game start and i can play and pass to level 2... my other coleco is fully stock so i cant test... on my normal adam it work perfectly too. i still have to test on my other adam that play sgm game with out the sgm in to see if the game works..

arcadevision your game is awesome and im sure you did all the beta testing on pal and ntsc colecovision...we cant blame you for the ntsc vram problem... by working on a fix for people who bought your game you show us respect and im sure for future game you will take a special care for those problematic vram ... i bought you game and will buy again if you release another one... we should apreciate more the effort to bring highclass game like risky rick... game like this raise the level of game for our loved system.. thank you

for people who bought the cart yes but for people who dont buy cart... collectorvision teampixelboy opcode they all knows who buying their games... we are a small groupe of people who buy all their games and the build around 75 to 100 copies of each games... exeption for some game like sydney,mario bros,pacman collection and maybe others but not that much... buy selling the rom after the cart are sold out they can get more potential cib customer...by putting info in the rom you prevent the share of roms.... most people here dump their cart play on atarimax and put the box on a shelf they dont even resale it...all publisher could put a copy of their game on ebay at the selling price and leave it there to prevent the high priced resale...

you could sell the rom like collectorvision did for the c64 version of sidney... if i remember right it was 5$us and do what you did with the demo by putting our name in the code... the guy who did dk on intellivision was doing it too by putting the paypal info in the code and nobody complain about it...

so it's drm... cause now the code have been change to not work on emulator or atarimax

works on my adam stand alone works on my f18a coleco with a little help😂 works perfectly on my 100% stock coleco now if the cant pass to level 2 is beacause a really thight timing ok but if its part of a drm its not working since people with fixed coleco have problem. finding a 100% stock working coleco today its realy hard.. vram is the most common problem on those system.. so the +5v vram is in a lot of coleco

ok got it to work on my f18a coleco by cycling the rocker switch off on fast and it pass to level 2... now im happy to be able to play on my main system but it suck that i cant put the game on my atarimax... hopefully they will release the game rom to people who bought the game when sold out for ever..they can put my name in the code like the demo version i dont care...

no mods on the adam... i have another one that play sgm game with no sgm in i will try if the game run fine or fail to pass to level 2

no sgm and i got the f18a screen i will retry again later and cycle it on and off ti see if i can get it to work

ok got my cart today... try on my f18a and it do nothing the game does not start... play on my adam work perfectly pass the screen to level 2... dump the cart burn the eprom game work on my f18a but dont pass to level 2 and dont pass to level 2 on the adam too so i dont know... maybe i will open my cart to see .. i will think about it...
