NES Rad Racer Score RAM Location/Format

NES Rad Racer Score RAM Location/Format

I've begun a project to parse out and store the high scores from certain 8 and 16 bit games in my Batocera cabinet.

Done about two dozen or so by either studying the CPU memory, or with the data from the fine folks at DataCrystal.

Working on Rad Racer, can't seem to understand what they were doing.

What I've been able to glean so far is that something is stored at $0031, up to decimal 83, hex 53

(Screen shots are from Mesen while game was paused)

At 84 it's rolled over to 00, and I can't seem to find any sort of multiplier

If I just do some random higher score.

Most games store their score contiguously, either as BCDs or hex values of the score 10 divisors. But I think there is some sort of multiplier somewhere else, since 1002 = 78 + (84*11), but I can't seem to find it.

I try to be patient, understanding and empathetic, but I just.... couldn't (Firehouse Subs)

Walked in during a slow time last week, I think right before dinner rush.

Was greeted, and responded. Studied the menu for a bit and decided on the Steak and Cheese.

Stated my order and the cashier was going through her script, but between her accent, her rapidity, her soft voice, the loud music, her talking towards her till, and the machinery, I simply could not understand her. Bread type took three repeats, veggies took four repeats, and after she got to, I think, the second repeat of the sides, I simply stated "I'm sorry, I'll have to come back another time" and asked her to cancel the order.

I'm a guy that already has exceedingly low expectations of retail staff, so that way I'm rarely disappointed. I don't leave reviews, I just simply won't go back.

I don't blame her. I blame her manager who obviously put her there before she was comfortable and ready.

And I will fully concede the veneer and subtext if the reader senses it, or at least a latent or subconscious bias. And that is what bothers me most. I don't want to be that guy. I just want a sandwich.

Heads up if you're interested in working for EA: They are now owned by Saudi Arabia

I have an unhealthy loathing of EA that goes back two decades for various reasons.

The newest one is that two days ago, the wholesale purchase of it was completed to the Saudi Arabia Public Investment Fund (95%), with the rest divided up between two other Venture Capital firms, one of which is owned by trump's son in law, Jared Kushner.

They have to pay off $18 billion in debt, which likely means cutbacks and layoffs, so they may not even be hiring here in Vancouver.

I like how we've collectively memory-holed the Section 31 movie

It's not in the subreddit 'Where to Start' page.

It's never mentioned in the routine "Beginner To Trek" question posts.

Never included on the routine "rank the movies" posts and replies.

Trek fans can be divisive - Kirk Vs. Picard, TOS vs Renaissance Shows vs Nu Trek, Best Warp Effects - but one thing we've all been able agree is that movie stunk to high heaven.

And I'm a fan who can find redeeming aspects of both 5 and Into Darkness and even Picard Season 2.

5 Hour Edit:

Glad this came back after getting memory-holed itself by the mods.

As objectively terrible as the movie was, it was somehow made worse by the ending. They were going to investigate Turkana 4, birthplace of Tasha Yar.

The decline and fall of a human colony? Yes please. Make it an allegory against the current world. You can even bring in Denise Crosby as the Yar matriarch trying to protect her two girls.

Mentioning Turkana 4 and fading to black was the ultimate blue balls after a very mediocre one night stand.

We were broke as dirt growing up - yet we always had TV Guide mailed to us

Man, that was a fun time getting it in the mail (or buying it, too). Opening it up, seeing the 2 line descriptions of your favourite shows, checking out the dedicated sections for movies.

Best way to grab high scores from emulators

Had an idea to grab scores for certain games and store them for later use.

I know MAME has that functionality, but I wanted it for NES, Genesis, etc.

Best method I could come up with was a BatoCera script that checks for gameEnd, checks if I wanted the score for that game, decompresses the auto save file, reads and builds the data from the memory, and curls that to another system that stores it in a database.

Works well enough, but the main limitation is having to research where in the memory the value I want is stored (and how it's stored) and build that into the script. I'll clean up that aspect, probably by just offloading totally it to this other system, and grabbing the save file from the share, but there's still the issue of figuring out where the score is. Though finding it really isn't the issue either. Some site I found has done a decent job of mapping a fair number of ROMs. But it's still game by game.

Just wondering if anyone has done that grunt work of grabbing the scores like this for the most popular of the games.

Thoughts on who the real Brian Spilner was?

It would have been easier at the time to take over an identity than to try craft a whole new one for Jesse to find. There's also the late 90s influences of Face/Off and Gattaca. And the original inspiration, Point Break, is too old for that plot point to matter.

So, Brian Earl Spilner. Probably around the same age as O'Connor. Did two years in a Juvenile detention facility in Tucson for boosting cars. Probably works as a labourer in a garage some where in Arizona. Was approached by the cops to allow his background to be used in exchange for wiping his record clean.

Rogers (formerly Shaw) Modem Intercepting All Traffic

Ever since Shaw-Now-Rogers only began offering Wi-Fi modems, I've ran them in bridge mode with my own equipment

Twice so far this year the modem, an SG4141SHW, seemed to go haywire and starting capturing all my traffic, redirecting all browser traffic to "myrouter.io"

My own router still responds via IP Address and status shows connected with my external IP address.

I don't try to log in - a reboot of the modem has worked both times.

Anyone know what the issue is? Botched firmware upgrade overnight?

Hope your TV was OK.

Followed behind them as they pulled out from the Visions parking lot. Honestly surprised they made it that far.

Arcade1Up Cabinets aren't really meant for commercial use, are they?

Went out to lunch yesterday at a place nearby, a family-oriented brewhouse. They have a section with 7 3/4-size Arcade1Up Machines, all free-to-play:

- A Street Fighter II cabinet with a broken Player 1 joystick.

- A 2 player NBA Jam Cabinet where both shoot buttons didn't work.

- A Star Wars: Return of the Jedi cab with half the yoke missing and a boot up error.

- A The Fast and the Furious cabinet with the rim of the steering wheel gone (the hub remained) along with both pedals. (the button actuators underneath remained)

- A wall mount that was off and unplugged.

- A WWF WrestleMania cabinet that did seem to work

- A wall mount with Pac-Man that was also working.

These machines are there to entertain the kids (and certain grown ups) while their food is being made. But seeing them all like that was pretty sad.

I briefly considered an Arcade1Up (to mod) a while back before I built mine, but decided it didn't seem worth it. My kids hammer on that thing, with the worst issue being some peeling paint on the control panel. (never covered with plastic)

Can someone tell me why neutral tow mode can't be used for dolly towing?

2025 STX with 4WD. We're unfortunately getting it towed to the dealer to deal with a "Parking Brake Fault. Service Immediately" error. Googled the best way to get/set it up for towing, thinking that neutral tow with the transmission in neutral on the dolly would be enough, but it's saying don't do that.

I'm still not clear why it can be used for 4-down towing, but not dolly towing.

What's Hiring Like in Canada?

(yes, I see rule 7 there)

Applied for a niche technical position. Low interest on the LinkedIn posting (people having clicked 'Apply'), but I don't know how many candidates go right for the dedicated careers site.

It matched me well, so I jazzed up my resume a bit and sent it in. Their auto reply didn't say anything about a time frame, or a closing date or anything.

Still says "Application Received" in the portal, coming up on three weeks now.

If they had any interest, would they have jumped a bit sooner?

Do they even use that portal for updating?

Thanks.

Ever ask if an FTE position can become a contract role for potential J2+?

Is that a thing? Does it work? Presumably, a company could be open to it as there's less liability on their end.

On the other end, thinking that a hiring manager may not want to lose an FTE for his department headcount.

Sometimes I get offended at the lack of effort, but then I remember that this is literally the best they're able to do. 🏆

Not personalized. Nothing specific about my profile. And of course "IT opportunities" in the second biggest country on the planet.

$36.60 per hour, eh? Yeah, f*** you Devry Greenhouses.

https://careers.devrygreenhouses.com/jobs/613316-it-support-team-lead-technical-support-supervisor

and on the Job Bank of course.

https://www.jobbank.gc.ca/jobsearch/jobposting/49520695

I suspect they want an LMIA for this one. That wage is the minimum for what's known as the "High Wage Stream" and doesn't have a cap on the number that can come in for that employer. They're also not restricted during high unemployment like the low-wage stream is.

The job has to posted for 4 weeks before they can apply for one. They're coming up on that soon.

It's a big paycut for me so I wouldn't accept it anyway, but I think I will apply just to mess them up, as I hit everything. They need to prove that they "exhausted" the local candidate pool to get an LMIA, but if a qualified candidate shows that they applied, they have show why they were not considered.

I really hate this shit.

Facets - Shouldn't Jadzia have more say in whether she gets Curzon's memories back?

We know from the first zhian'tara that Jadzia actually loses the memories when they're transferred. I remember she found it unsettling. We also been told that the current host draws upon the experiences of all the previous hosts, so she would be losing an important.. well, facet of herself.

There's no way of knowing, but it does seem doubtful that Curzon would be the first prior host to want to stay separated in that ceremony, so the Trill may have ways of dealing with it.

Also raises some philosophical and legal questions . Do the memories belong to the current host? During the ceremony, is the prior host an actual person with agency over themselves?

I need to avoid watching U7 on Youtube.

Watching some of these teams, lining up on cue, understanding and running plays, throwing 20 yard passes that get caught.

Then I see my little girls' U7 coed team in a local rec league, (I'm coaching), and still having to tell some of them to face the other team at the line of scrimmage while not pulling their own teammate's flags.

I know the point is to have fun (and the videos are showing the elite at even this age), but holy god, I'm glad I never became a teacher.
