Arcade games non jtag console

ok so i been working on trying to get arcade games that i downloaded to work on non jtagged consoles. im using a usb stick to transfer the content.as you know you just cant take the game and drop it on the usb using USBXTAFGUI_v31 b/c you'll get a corrupted file. so i decided to take a game off my hdd (hexic hd) and put it on my usb as a reference to see how the keys and id's looked on a full arcade game that i own. so loaded the game with Le Fluffie App and compared the games. on hexic hd if you click verify and scroll all the way down the signatures at the bottom read
like so signature---22C---4--True
signature---22C---4--False
on the arcade game i downloaded it reads
signature---22C---4--False
signature---22C---4--False
ok,.. so with the option sign for CON checked i clicked "fix" i then hit verify and it shows signature---22C---4--False
signature---22C---4--True
so i extracted it to my desktop and opened up USBXTAFGUI_v31. and dragged it to the right spot and then loaded it up on my 360 slim. it shows up on the usb stick without saying its corrupted and allows me to copy/move it to my hdd. and i noticed that if you go to marketplace/arcade under that game it says play trail and not get trail. so i went to my xbox-games. it doesnt show up but for like a brief sec like .5 of a second and it wont be there. so i went back to marketplace/arcade hit play trail but to no avail it acts like its bout to load but just fades out and shows the normal screen again. so is there anyone else out there workiong on this besides myself to get arcade games working on us non jtagged users ? i'll try and post a video to show all of what i just said if all this didnt make sense
