Had a brief chance to play this morning and improved a bit: 17,951

Yes, it was fine. Looks like no-one remembers it (it's Flickr - I misspelled it before). Here: POKEY upside down, large as life.

Happy Computing moved on from the Atari 8 bit and made an Atari ST cartridge that would flux copy most SSDD and DSDD floppy disks. https://en.wikipedia.org/wiki/Happy_drives It needs a straight cable and I think it came with one. I have one in my garage somewhere as I now use Greaseweazle when necessary.

but won't work once you convert it to a memory image file (option 5).

Greetings Programs! So for A7800DS emulation, my bible for High Score Cart format has been @RevEng's amazing resource: However, I've discovered that some later homebrews (e.g. Popeye) are a bit finicky about the state of the SRAM contents. If I don't run something like Asteroids (NTSC) to initialize the SRAM, the junk values seem to cause Popeye to show trash scores (mixing letters/numbers, etc). Understandable - so I initialize the HSC SRAM with Asteroids and I still get some behavior that I'm trying to understand. I assume the initialization would initialize all 2K of the SRAM but it doesn't - some of the bytes are not touched so it's whatever I had in my emulated SRAM buffer. And these two snapshots represent a HSC SRAM that was cleanly initialized by Asteroids (NTSC) with the same cartridge name ("HSC"). The rightmost one had the initial SRAM buffer loaded with FF values. The leftmost one had 00 (zero) values. In the case where my uninitialized SRAM buffer initially contained 0xFF values, a game like PopEye will pre-populate high-scores with a non-nonsensical EEEEEE. In the case where my uninitialized SRAM buffer initially contained 0x00 values, a game like PopEye will pre-populate high-scores properly with 0s (zeros) but it also disables some of the features such as Brutus throwing 4 (four) bottles and the Novice mode background being red (i.e. the flag that is saved for that feature is clear). I realize that a game should NOT care what (probably random) state the SRAM is in and should initialize things to a proper state - but it begs the question as to what is the most likely state of real uninitialized SRAM on a high score cart? That is, before battery power is applied and a cart initializes (formats) the HSC area... I assume the values would be random? I think A7800js is zeroing the SRAM buffers before initialization. Unsure what A7800 is doing for SRAM memory init. Any thoughts, clues or random mussings appreciated! Lastly - not trying to throw shade on the amazing 7800 port of Popeye ... it's just the latest game that is giving my emulator a workout these days.

Now that I’m hooked on this game the levels are extremely tough! Who would have thought they could make a game where you can’t see a fcukn thing! 😎

What do you mean "Discovery Cartridge"?

Looking forward to playing Desmond's or Hobgoblin, both good games!

GenWIPE grabs all open memory pages and clears them. When the object files are linked and saved to a program image, any non-code space & reserved space (e.g. BSS) will have been set to >00. It results in a much cleaner file and no ‘random’ info littered all over the program. LINK should be doing this IMHO but either Paul felt the obfuscation was a good hedge against disassembly or he just didn’t consider it important enough to implement. (/4a linkers like RAG initialize the space first.)

Yes it should be a straight cable with no crossovers. You need one with a Discovery Cartridge too.

Did POKEY survive? What FLIKR album are we talking about? I don't remember that...

I agree with @Crazy Climber. It's probably genuine Atari "something". Could have been used by Atari for a trade show, could have hung on an Atari executives wall, could have been given to the artist as a proof or gift, etc. It looks old enough to be from that time period, anyhow. Now if that makes it valuable or not, I can't say....

Thank you for your explanation into PIA pullups concerning the design of the Rambo XL. Yesterday I measured the R6520 PIA pins in a RamboXL modified 800XL to compare with someone else's 800XL and can confirm that PB12-PB16 are showing nice and high with a voltmeter so must be being pulled up.

Hi! Not getting any RAM at MEDIUM MEMORY(>7000->7FFF). This makes MINI MEMORY's @LOADER, fail.

You could also plug the GSP power cord's USB connector into your TV's USB port to power the GSP. If it doesn't work with larger AC adapters or plugged into the TV, then return/exchange it.

Thanks! So it it PIN 1 - PIN 1 PIN 2 - PIN 2 PIN 3 - PIN 3 etc?

I'd have to check but I don't think Plaion France wanted any extension cables.

Stock is being delivered to Plaion DC and Ataris DC at the same time.

Italy it’s well known for its tremendous efficiency!🤣🤣🤣🤣 Rog, it could be nice to add, next to the participants names, the arrival and departure date… Not for judging people of course, anyone can take as much time as he wants, just to better see the whole lootbox journey… Actally, I saw in the list that wolfy is in the US but I thought he was in Canada… @wolfy62 where are u? I noticed that in the lootbox there is also a Baseball FCTVVO, nice! Last question: who did put the 25 videogames system I took? Just curious…

Cool. Good luck finishing that deal. Phew, that's a pretty high score, already. Well done, Brett! . o O (Who can stop this guy winning every monthly round?)

Street Racer and Hellway 2PE may look similar, but there is a big difference!

Small extension to mid-day tomorrow (6th May) as it's a Holiday here in the UK No improvement from me so I can get another go or ten in Anyone not voted? The R7 McKong Poll is still open: https://forums.atariage.com/topic/365551-hsc21-round-7-poll/
