Trebor

Honestly, it's not really my style either. I originally was hoping and thinking it is more action/adventure based and less puzzle. The game though is that amazingly good, I had to play it through, and very glad I did. It's fantastic! Additionally, the developer can still be supported... http://www.penguinet.net/Games/Rikki_Vikki/Purchase/index.php Currently, it is on sale through January 5 for only $1.99 under Steam: Further, it can be purchased via Humble Bundle (No DRM) at the regular price of $9.99 with the option to leave the developer a tip:

Version 1.0.0 of this excellently done fan remake was released. Freely available for Windows, MacOS, Linux, and even a VR-only build for items such as the Oculus Rift, HTC Vive, and OpenVR/SteamVR compatible headsets. For those interested, what's new for this release is provided.

In case you are not aware... If you're Jonesing for a less colorized looking Space Invaders under the 7800, such an option is present under Bob's fantastic Space Invaders port. To retain more of the 2600 feel, but the look of the Arcade original, there is Space Invaders Arcade available as well. Another option is Space Instigators.

Amazing how much is learned over time, as well as the variety of approaches and techniques that can be applied. Here is a similar end result, but with 101 sprites and no flickering or slowdown of movement: 7800basic is a fantastic piece of software. The above is just one example. Much of the explosion in 7800 game development is a strong testimony to it.

Rygar - Absolute favorite 8-bit console game. I never saw or played the Arcade game in its heyday, and was actually disappointed to experience the Arcade original years later under emulation (Via REM!) circa '97, as it vastly differs from the NES port. I perform a complete playthrough of NES Rygar at least once a year for over 30+ years. Three times this year.

You likely have one of the earlier carts with that issue. Fred mentioned fixing the issue with newer carts that went out. 5l4k3r just recently receiving his cart, already has one with the fix in place. Fred also related, "...for the small number of carts out there without the fix, there are plans to improve the Harmony programming software to work around the communication issue. For now, though, try removing the POKEY, do the update then reinsert."

...NEXT STOP...

Thanks to 2600 Ms. Pac-Man, I often refer to an easy difficulty setting as 'Teddy Bear' mode. 🧸 When I hear something is described as heavy, my mind references Back To The Future and the conversation between Marty and Doc Brown... Marty: Are you telling me that my mom has got the hots for me? Doc Brown: Precisely. Marty: Whoa, this is heavy... Doc Brown: There's that word again, heavy. Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?

Some USB cables are charge only, lacking data receive and transfer wires, they have only positive and negative lines present. It drove me nuts due to not knowing that tidbit several years back when working with the Harmony cart. *EDIT: Sorry, responded to the quoted portion before seeing RevEng's and Jinks' spot-on posts above. Both beat me to the punch...lol.

Thanks to the information provided by John Harvey for the below details... ============================================================= Error codes While disassembling the code, I found some of the error codes. Note that the error code is sent to the "Yuk face" routine as a hex code on the Y-register, which is then translated. $0 thru $9 translate to 0 thru 9, and $A translates to "X". Here is the list that I've accumulated: 01 - Failure to debounce either the reset switch or select switch 02 - RAM $0480 - $04FF error 03 - Diagnostic cart is running on a 2600 (cannot store to $2000) 04 - Status flags or stack error 05 - Failure of a PIA Timer 06 - Control port failure; occurs if not using proper diagnostic plugs or if the SWCHA ports are broken 07 - INPT failure; occurs if not using proper diagnostic plugs or if there is a failure in one of the INPT registers on the PIA 08 - diagnostic plug failure (if I remember right, this has to do with not having the 47 k-ohm resistors on the plugs. I will re-investigate later. 11 - RAM $0140 - $01FF error 12 - RAM $0040 - $00FF error 14 - $FFF9 error-- Either the left nibble at $FFF9 does not contain a valid bank size (i.e. > 48K) or the right nibble isn't 7. Error codes in the code that I haven't figured out (yet): 1) Numeric codes: X0, X1, X2, X3, and X4 -- I found these codes in the following code segment: ;;;;;;;;; START CODE ;;;;;;;;;;;;;;;;;; LF884: LDA $F88B,Y ; $B9,$8B,$F8 TAY ; $A8 JMP $F026 LF88B: ; SIX error codes used by F884. dc.b $A4 ; will display "X4" dc.b $A1 ; will display "X1 dc.b $A2 ; will display "X2 dc.b $A0 ; will display "X0 dc.b $A3 ; will display "X3 dc.b $03 ; will display "03 ;;;;;;;;;;; END CODE ;;;;;;;;;;;;;;;;;; Note that there are also other errors that are not caught with an "error code". For example, on the first screen where it says "7800 PRO SYSTEM DIAGNOSTIC TEST VERSION 1:00", you can also somehow trigger text that says " BAD!!!!!". This is found at $EB87, the third chunk of character map data, to be stored at $191E. ============================================================= @Mitch too provided some insight and results experience with "X4" as well: X4 - I got this error when I installed the standard NTSC OS in a PAL machine. I also got it once when I hit a console button at the color adjustment screen. ============================================================= The Diagnostic Cart is a part of Trebors 7800 ROM PROPack. Posting the image here for convenience as well for anyone else that would like to leverage it: Diagnostic Test Cartridge (19xx) (Atari).a78 Want your own copy? Best Electronics has it... @Swami Did you opt for the Universal NTSC/PAL BIOS with built-in Asteroids mod ("7800 Euro Operating System Upgrade") for your Best 7800 console? The cartridge itself will not run at all on such a unit (I have both the cart and a Best Electronics mod with OS upgrade), but just the ROM image itself on a 'flash cart', I have not tried.

Or just click here. It's part of Trebors 7800 ROM PROPack, too.

Imagine the notion of console game developers wanting to have their game on actual physical standalone cartridges. They may even want to see a box and manual published for their game too. A whole store could be built around this premise.

👍 Ditto (On all three statements ) Certainly, there have been Gumby talks previously; however, never heard of a 'Mini Gumby' specifically being mentioned, or this amount of detail. Maybe it was due to the very low attendance that year, per Marty. Searching the forums for both CGE 2K12 and CGE 2012 yields zilch about 7800 specific material from back then.

Seconded! Swapping the "X" for a "Y" and it's good to go. XM SOUND --> YM SOUND XM ENHANCED --> YM ENHANCED

Maybe this will help:

I thought it was found and was planning another trip (Circa 2009). Unsure if that ever came to fruition. Multiple copies were made ~six months after the original one took off on its travels. For those multiple copies, a game (Hack of Gosub for the 2600) was added instead of the 3 screen demo of the original. It's also really a 2600 ROM though, along the lines of "Save Mary" being 'for the 7800' without needing any of the latter's memory requirements. It's not accessing MARIA for graphics. It's all TIA with a small footprint 4K: It's playable (Press Reset to start). Travi continues to glide/float in the last direction it was pressed in without stopping... ...Travi needs to reach that rectangle without touching the walls... Travi evidently went from a Mogwai to a Gremlin while visiting Cousin Vinnie.

No. Original Travi is a three screens demo cart. The screens are changed by pressing the fire button. First screen is the title/intro screen. Press the fire button and it brings up the second screen, a picture of Travi. A third press of the fire button shows a map of the world. It likes (liked?) to travel.

In the 20202012 build, the Roachy is still listing as $300, but only requires and takes $200 when purchased in the store. Loving the Firing Dragon mini-game addition! Different enemies with changed/Diagonal attack patterns too! Ohhh... and the Cosmic Ark-ish attack on Knight Guy! The Spinning Skulls are a nice touch to that mini-game, the upgrade to the obstacle course, as well as the status display in the 'Breakout Boss' battle. Just for some fun scares...

My pleasure. In the video's beginning it may be noticed, there's a little back a forth between the options at the title screen. One reason was to show what was available, but another huge reason is to find where the paddle controls 'kick-in' and picks up the clock and counter-clockwise movements of the controller. One humble suggestion here is perhaps for a game to start without the ball or field moving - just allowing the paddle to move up and down. It allows the player to find the 'sweet' spot for paddle movement. Once the player acclimates to the paddle control and sensitivity, the button on the paddle control is pressed, ball is released, and then the game starts where it currently begins now.

Love the smooth animation of the enemy patterns, especially when so many of them in a constant swirl like movement. The cooperative play is a great touch as well.

I have to agree with Vinnie here. Granted, much, if not all of this, is subjective. Nonetheless, just because a port matches an Arcade game - even exactly, doesn't mean it scores high(er). If a horrible looking, sounding, and playing Arcade game is ported perfectly to the 7800, does not mean it earns high marks across the board. What there should be perhaps present, when grading an Arcade port, is another category "Likeness to Arcade", or something along those lines. There it would receive its higher grade.

Just a quick play video spreading a little more love...I do need more practice though:
